The HYS72Dxx5x0GR are low profile versions of the standard Registered DIMM modules with 1.2”
inch (30,40 mm) height for 1U Server Applications. The Low Profile DIMM versions are available as
16M x 72 (128MB) and 32M x 72 (256MB).
The memory array is designed with Double Data Rate Synchronous DRAMs for ECC applications.
All control and address signals are re-driven on the DIMM using register devices and a PLL for the
clock distribution. This reduces capacitive loading to the system bus, but adds one cycle to the
SDRAM timing. A variety of decoupling capacitors are mounted on the PC board. The DIMMs
feature serial presence detect based on a serial E2PROM device using the 2-pin I2C protocol. The
first 128 bytes are programmed with configuration data and the second 128 bytes are available to
the customer.

1) The relationship between the VDDQ of the driving device and the VREF of the receiving device is what
determines noise margins. However, in the case of VIH (max) (input overdrive), it is the VDDQ of the receiving
device that is referenced. In the case where a device is implemented such that it supports SSTL_2 inputs but
has no SSTL_2 outputs (such as a translator), and therefore no VDDQ supply voltage connection, inputs must
tolerate input overdrive to 3.0 V (High corner VDDQ + 300 mV).
2) For any pin under test input of 0 V ≤ VIN ≤ VDDQ + 0.3 V. Values are shown per DDR-SDRAM component.

1. Input slew rate >=1V/ns for DDR266 and = 1V/ns for DDR200.
2. The CK/CK input reference level (for timing reference to CK/CK) is the point at which CK and CK cross: the input reference
level for signals other than CK/CK, is VREF. CK/CK slew rate are >= 1.0 V/ns.
3. Inputs are not recognized as valid until VREF stabilizes.
4. The Output timing reference level, as measured at the timing reference point indicated in AC Characteristics (Note 3) is VTT
.
5. tHZ and tLZ transitions occur in the same access time windows as valid data transitions. These parameters are not referred
to a specific voltage level, but specify when the device is no longer driving (HZ), or begins driving (LZ).
6. The maximum limit for this parameter is not a device limit. The device operates with a greater value for this parameter, but
system performance (bus turnaround) degrades accordingly.
7. The specific requirement is that DQS be valid (HIGH, LOW, or some point on a valid transition) on or before this CK edge.
A valid transition is defined as monotonic and meeting the input slew rate specifications of the device. When no writes were
previously in progress on the bus, DQS will be transitioning from Hi-Z to logic LOW. If a previous write was in progress,
DQS could be HIGH, LOW, or transitioning from HIGH to LOW at this time, depending on tDQSS
.
8. A maximum of eight Autorefresh commands can be posted to any given DDR SDRAM device.
9. For each of the terms, if not already an integer, round to the next highest integer. tCK is equal to the actual system clock
cycle time.
10. These parameters guarantee device timing, but they are not necessarily tested on each device
11. Fast slew rate >= 1.0 V/ns , slow slew rate >= 0.5 V/ns and < 1V/ns for command/address and CK & CK slew rate >1.0 V/
ns, measured between VOH(ac) and VOL(ac)

Registered DDR-I SDRAM-Modules
APPLICATION NOTE:
Power Up and Power Management on DDR Registered DIMMs
(according to JEDEC ballot JC-42.5 Item 1173)
184-pin Double Data Rate (DDR) Registered DIMMs include two new features to facilitate controlled power-up
and to minimize power consumption during low power mode. One feature is externally controlled via a system-
generated RESET signal; the second is based on module detection of the input clocks. These enhancements
permit the modules to power up with SDRAM outputs in a High-Z state (eliminating risk of high current dissipa-
tions and/or dotted I/Os), and result in the powering-down of module support devices (registers and Phase-
Locked Loop) when the memory is in Self-Refresh mode.
The new RESET pin controls power dissipation on the module’s registers and ensures that CKE and other
SDRAM inputs are maintained at a valid ‘low’ level during power-up and self refresh. When RESET is at a low
level, all the register outputs are forced to a low level, and all differential register input receivers are powered
down, resulting in very low register power consumption. The RESET pin, located on DIMM tab #10, is driven
from the system as an asynchronous signal according to the attached details. Using this function also permits the
system and DIMM clocks to be stopped during memory Self Refresh operation, while ensuring that the SDRAMs
stay in Self Refresh mode.
The function for RESET is as follows:

X : Don’t care, Hi-Z : High Impedance, Qo: Data latched at the previous of CK
risning and CK falling
As described in the table above, a low on the RESET input ensures that the Clock Enable (CKE) signal(s) are
maintained low at the SDRAM pins (CKE being one of the 'Q' signals at the register output). Holding CKE low
maintains a high impedance state on the SDRAM DQ, DQS and DM outputs — where they will remain until acti-
vated by a valid ‘read’ cycle. CKE low also maintains SDRAMs in Self Refresh mode when applicable.
The DDR PLL devices automatically detect clock activity above 20MHz. When an input clock frequency of
20MHz or greater is detected, the PLL begins operation and initiates clock frequency lock (the minimum operat-
ing frequency at which all specifications will be met is 95MHz). If the clock input frequency drops below 20MHz
(actual detect frequency will vary by vendor), the PLL VCO (Voltage Controlled Oscillator) is stopped, outputs are

made High-Z, and the differential inputs are powered down — resulting in a total PLL current consumption of less
than 1mA. Use of this low power PLL function makes the use of the PLL RESET (or G pin) unnecessary, and it is
tied inactive on the DIMM.
This application note describes the required and optional system sequences associated with the DDR Regis-
tered DIMM 'RESET' function. It is important to note that all references to CKE refer to both CKE0 and CKE1 for
a 2-bank DIMM. Because RESET applies to all DIMM register devices, it is therefore not possible to uniquely
control CKE to one physical DIMM bank through the use of the RESET pin.
Power-Up Sequence with RESET — Required
1. The system sets RESET at a valid low level.
This is the preferred default state during power-up. This input condition forces all register outputs to a low
state independent of the condition on the register inputs (data and clock), ensuring that CKE is at a stable
low-level at the DDR SDRAMs.
2. The power supplies should be initialized according to the JEDEC-approved initialization sequence for DDR
SDRAMs.
3. Stabilization of Clocks to the SDRAM
The system must drive clocks to the application frequency (PLL operation is not assured until the input clock
reaches 20MHz). Stability of clocks at the SDRAMs will be affected by all applicable system clock devices,
and time must be allotted to permit all clock devices to settle. Once a stable clock is received at the DIMM
PLL, the required PLL stabilization time (assuming power to the DIMM is stable) is 100 microseconds. When
a stable clock is present at the SDRAM input (driven from the PLL), the DDR SDRAM requires 200 µsec prior
to SDRAM operation.
4. The system applies valid logic levels to the data inputs of the register (address and controls at the DIMM con-
nector).
CKE must be maintained low and all other inputs should be driven to a known state. In general these com-
mands can be determined by the system designer. One option is to apply an SDRAM ‘NOP’ command (with
CKE low), as this is the first command defined by the JEDEC initialization sequence (ideally this would be a
‘NOP Deselect’ command). A second option is to apply low levels on all of the register inputs to be consistent
with the state of the register outputs.
5. The system switches RESET to a logic ‘high’ level.
The SDRAM is now functional and prepared to receive commands. Since the RESET signal is asynchronous,
setting the RESET timing in relation to a specific clock edge is not required (during this period, register inputs
must remain stable).
6. The system must maintain stable register inputs until normal register operation is attained.
The registers have an activation time that allows their clock receivers, data input receivers, and output drivers
sufficient time to be turned on and become stable. During this time the system must maintain the valid logic
levels described in step 5. It is also a functional requirement that the registers maintain a low state at the CKE
outputs to guarantee that the DDR SDRAMs continue to receive a low level on CKE. Register activation time
(t (ACT) ), from asynchronous switching of RESET from low to high until the registers are stable and ready to
accept an input signal, is specified in the register and DIMM do-umentation.
7. The system can begin the JEDEC-defined DDR SDRAM power-up sequence (according to the JEDEC-
pproved initialization sequence).
Self Refresh Entry (RESET low, clocks powered off) — Optional
Self Refresh can be used to retain data in DDR SDRAM DIMMs even if the rest of the system is powered down
and the clocks are off. This mode allows the DDR SDRAMs on the DIMM to retain data without external clocking.
Self Refresh mode is an ideal time to utilize the RESET pin, as this can reduce register power consumption
(RESET low deactivates register CK and CK, data input receivers, and data output drivers).

1. The system applies Self Refresh entry command.
(CKE→Low, CS→Low, RAS → Low, CAS→ Low, WE→ High)
Note: The commands reach the DDR SDRAM one clock later due to the additional register pipelining on a
Registered DIMM. After this command is issued to the SDRAM, all of the address and control and clock input
conditions to the SDRAM are Don’t Cares— with the exception of CKE.
2. The system sets RESET at a valid low level.
This input condition forces all register outputs to a low state, independent of the condition on the registerm
inputs (data and clock), and ensures that CKE, and all other control and address signals, are a stable low-
level at the DDR SDRAMs. Since the RESET signal is asynchronous, setting the RESET timing in relation to
a specific clock edge is not required.
3. The system turns off clock inputs to the DIMM. (Optional)
a. In order to reduce DIMM PLL current, the clock inputs to the DIMM are turned off, resulting in High-Z clock
inputs to both the SDRAMs and the registers. This must be done after the RESET deactivate time of the reg-
ister (t (INACT) ). The deactivate time defines the time in which the clocks and the control and address sig-
nals must maintain valid levels after RESET low has been applied and is specified in the register and DIMM
documentation.
b. The system may release DIMM address and control inputs to High-Z.
This can be done after the RESET deactivate time of the register. The deactivate time defines the time in
which the clocks and the control and the address signals must maintain valid levels after RESET low has
been applied. It is highly recommended that CKE continue to remain low during this operation.
4. The DIMM is in lowest power Self Refresh mode.
Self Refresh Exit (RESET low, clocks powered off) — Optional
1. Stabilization of Clocks to the SDRAM.
The system must drive clocks to the application frequency (PLL operation is not assured until the input clock
reaches ~20MHz). Stability of clocks at the SDRAMs will be affected by all applicable system clock devices,
and time must be allotted to permit all clock devices to settle. Once a stable clock is received at the DIMM
PLL, the required PLL stabilization time (assuming power to the DIMM is stable) is 100 microseconds.
2. The system applies valid logic levels to the data inputs of the register (address and controls at the DIMM con-
nector).
CKE must be maintained low and all other inputs should be driven to a known state. In general these com-
mands can be determined by the system designer. One option is to apply an SDRAM ‘NOP’ command (with
CKE low), as this is the first command defined by the JEDEC Self Refresh Exit sequence (ideally this would
be a ‘NOP Deselect’ command). A second option is to apply low levels on all of the register inputs, to be con-
sistent with the state of the register outputs.
3. The system switches RESET to a logic ‘high’ level.
The SDRAM is now functional and prepared to receive commands. Since the RESET signal is asynchronous,
RESET timing relationship to a specific clock edge is not required (during this period, register inputs must
remain stable).
4. The system must maintain stable register inputs until normal register operation is attained.
The registers have an activation time that allows the clock receivers, input receivers, and output drivers suffi-
cient time to be turned on and become stable. During this time the system must maintain the valid logic levels
described in Step 2. It is also a functional requirement that the registers maintain a low state at the CKE out-
puts to guarantee that the DDR SDRAMs continue to receive a low level on CKE. Register activation time (t
(ACT) ), from asynchronous switching of RESET from low to high until the registers are stable and ready to
accept an input signal, is specified in the register and DIMM do-umentation.
5. System can begin the JEDEC-defined DDR SDRAM Self Refresh Exit Procedure.

Although keeping the clocks running increases power consumption from the on-DIMM PLL during self refresh,
this is an alternate operating mode for these DIMMs.
1. System enters Self Refresh entry command.
(CKE→ Low, CS→ Low, RAS→ Low, CAS→ Low, WE→ High)
Note: The commands reach the DDR SDRAM one clock later due to the additional register pipelining on a
Registered DIMM. After this command is issued to the SDRAM, all of the address and control and clock input
conditions to the SDRAM are Don’t Cares — with the exception of CKE.
2. The system sets RESET at a valid low level.
This input condition forces all register outputs to a low state, independent of the condition on the data and
clock register inputs, and ensures that CKE is a stable low-level at the DDR SDRAMs.
3. The system may release DIMM address and control inputs to High-Z.
This can be done after the RESET deactivate time of the register (t (INACT) ). The deactivate time describes
the time in which the clocks and the control and the address signals must maintain valid levels after RESET
low has been applied. It is highly recommended that CKE continue to remain low during the operation.
4. The DIMM is in a low power, Self Refresh mode.
Self Refresh Exit (RESET low, clocks running) — Optional
1. The system applies valid logic levels to the data inputs of the register (address and controls at the DIMM con-
nector).
CKE must be maintained low and all other inputs should be driven to a known state. In general these com-
mands can be determined by the system designer. One option is to apply an SDRAM ‘NOP’ command (with
CKE low), as this is the first command defined by the Self Refresh Exit sequence (ideally this would be a
‘NOP Deselect’ command). A second option is to apply low levels on all of the register inputs to be consistent
with the state of the register outputs.
2. The system switches RESET to a logic 'high' level.
The SDRAM is now functional and prepared to receive commands. Since the RESET signal is asynchronous,
it does not need to be tied to a particular clock edge (during this period, register inputs must continue to
remain stable).
3. The system must maintain stable register inputs until normal register operation is attained.
The registers have an activation time that allows the clock receivers, input receivers, and output drivers suffi-
cient time to be turned on and become stable. During this time the system must maintain the valid logic levels
described in Step 1. It is also a functional requirement that the registers maintain a low state at the CKE out-
puts in order to guarantee that the DDR SDRAMs continue to receive a low level on CKE. This activation
time, from asynchronous switching of RESET from low to high, until the registers are stable and ready to
accept an input signal, is t (ACT ) as specified in the register and DIMM documentation.
4. The system can begin JEDEC defined DDR SDRAM Self Refresh Exit Procedure.
Self Refresh Entry/Exit (RESET high, clocks running) — Optional
As this sequence does not involve the use of the RESET function, the JEDEC standard SDRAM specification
explains in detail the method for entering and exiting Self Refresh for this case.
Self Refresh Entry (RESET high, clocks powered off) — Not Permissible
In order to maintain a valid low level on the register output, it is required that either the clocks be running and the
system drive a low level on CKE, or the clocks are powered off and RESET is asserted low according to the

sequence defined in this application note. In the case where RESET remains high and the clocks are powered
off, the PLL drives a High-Z clock input into the register clock input. Without the low level on RESET an unknown
DIMM state will result.
