1. Input / Output Pin Function
Pin name
Input / Output
Input
Function
CLK
CKE
CLK is the master clock input. Other inputs signals are referenced to the CLK rising
edge.
Input
CKE determine validity of the next CLK (clock). If CKE is high, the next CLK rising
edge is valid; otherwise it is invalid. If the CLK rising edge is invalid, the internal clock
is not issued and the µPD4564323 suspends operation.
When the µPD4564323 is not in burst mode and CKE is negated, the device enters
power down mode. During power down mode, CKE must remain low.
/CS
Input
Input
Input
/CS low starts the command input cycle. When /CS is high, commands are ignored
but operations continue.
/RAS, /CAS, /WE
A0 - A10
/RAS, /CAS and /WE have the same symbols on conventional DRAM but different
functions. For details, refer to the command table.
Row Address is determined by A0 - A10 at the CLK (clock) rising edge in the active
command cycle.
Column Address is determined by A0 - A7 at the CLK rising edge in the read or write
command cycle.
A10 defines the precharge mode. When A10 is high in the precharge command cycle,
all banks are precharged; when A10 is low, only the bank selected by BA0 and BA1 is
precharged.
When A10 is high in read or write command cycle, the precharge starts automatically
after the burst access.
BA0, BA1
Input
Input
BA0 and BA1 are the bank select signal. In command cycle, BA0 and BA1 low select
bank A, BA0 low and BA1 high select bank C, BA0 high and BA1 low select bank B
and then BA0 and BA1 high select bank D.
DQM0 - DQM3
DQM controls I/O buffers. DQM0 controls DQ0 - DQ7, DQM1 controls DQ8 - DQ15,
DQM2 controls DQ16 - DQ23, DQM3 controls DQ24 - DQ31.
In read mode, DQM controls the output buffers like a conventional /OE pin.
DQM high and DQM low turn the output buffers off and on, respectively.
The DQM latency for the read is two clocks.
In write mode, DQM controls the word mask. Input data is written to the memory cell if
DQM is low but not if DQM is high.
The DQM latency for the write is zero.
DQ0 - DQ31
Input / Output
(Power supply)
DQ pins have the same function as I/O pins on a conventional DRAM.
VCC, VSS, VCCQ,
VSSQ
VCC and VSS are power supply pins for internal circuits. VCCQ and VSSQ are power
supply pins for the output buffers.

5. Initialization
The synchronous DRAM is initialized in the power-on sequence according to the following.
(1) To stabilize internal circuits, when power is applied, a 100 µs or longer pause must precede any signal toggling.
(2) After the pause, all banks must be precharged using the Precharge command (The Precharge all banks
command is convenient).
(3) Once the precharge is completed and the minimum tRP is satisfied, the mode register can be programmed. After
the mode register set cycle, tRSC (2 CLK minimum) pause must be satisfied as well.
(4) Two or more CBR (Auto) refresh must be performed.
Remarks 1. The sequence of Mode register programming and Refresh above may be transposed.
2. CKE and DQM must be held high until the Precharge command is issued to ensure data-bus Hi-Z.
18
Data Sheet E0114N10
µPD4564323 for Rev. E
6. Programming the Mode Register
The mode register is programmed by the Mode register set command using address bits A10 through A0, BA0 and
BA1 as data inputs. The register retains data until it is reprogrammed or the device loses power.
The mode register has four fields;
Options
/CAS latency : A6 through A4
Wrap type : A3
: A10 through A7, BA0, BA1
Burst length : A2 through A0
Following mode register programming, no command can be issued before at least 2 CLK have elapsed.
/CAS Latency
/CAS latency is the most critical of the parameters being set. It tells the device how many clocks must elapse
before the data will be available.
The value is determined by the frequency of the clock and the speed grade of the device. 13.3 Relationship
between Frequency and Latency shows the relationship of /CAS latency to the clock period and the speed grade of
the device.
Burst Length
Burst Length is the number of words that will be output or input in a read or write cycle. After a read burst is
completed, the output bus will become Hi-Z.
The burst length is programmable as 1, 2, 4, 8 or full page.
Wrap Type (Burst Sequence)
The wrap type specifies the order in which the burst data will be addressed. This order is programmable as either
“Sequential” or “Interleave”. The method chosen will depend on the type of CPU in the system.
Some microprocessor cache systems are optimized for sequential addressing and others for interleaved addressing.
7.1 Burst Length and Sequence shows the addressing sequence for each burst length using them. Both
sequences support bursts of 1, 2, 4 and 8. Additionally, sequence supports the full page length.

9. Precharge
The precharge command can be issued anytime after tRAS (MIN.) is satisfied.
Soon after the precharge command is issued, precharge operation performed and the synchronous DRAM enters
the idle state after tRP is satisfied. The parameter tRP is the time required to perform the precharge.
The earliest timing in a read cycle that a precharge command can be issued without losing any data in the burst is
as follows.
It is depending on the /CAS latency and clock cycle time.

(tRAS must be satisfied)
In order to write all data to the memory cell correctly, the asynchronous parameter “tDPL” must be satisfied. The
tDPL(MIN.) specification defines the earliest time that a precharge command can be issued. Minimum number of clocks
is calculated by dividing tDPL(MIN.) with clock cycle time.
In summary, the precharge command can be issued relative to reference clock that indicates the last data word is
valid. In the following table, minus means clocks before the reference; plus means time after the reference.

10. Auto Precharge
During a read or write command cycle, A10 controls whether auto precharge is selected. A10 high in the Read or
Write command (Read with Auto precharge command or Write with Auto precharge command), auto precharge is
selected and begins automatically.
The tRAS must be satisfied with a read with auto precharge or a write with auto precharge operation. In addition, the
next activate command to the bank being precharged cannot be executed until the precharge cycle ends.
In read cycle, once auto precharge has started, an activate command to the bank can be issued after tRP has been
satisfied.
In write cycle, the tDAL must be satisfied to issue the next activate command to the bank being precharged.
The timing that begins the auto precharge cycle depends on both the /CAS latency programmed into the mode
register and whether read or write cycle.
10.1 Read with Auto Precharge
During a read cycle, the auto precharge begins one clock earlier (/CAS latency of 2) or two clocks earlier (/CAS
latency of 3) the last data word output.

11. Read / Write Command Interval
11.1 Read to Read Command Interval
During a read cycle, when new Read command is issued, it will be effective after /CAS latency, even if the previous
read operation does not completed. READ will be interrupted by another READ.
The interval between the commands is 1 cycle minimum. Each Read command can be issued in every clock
without any restriction.

11.2 Write to Write Command Interval
During a write cycle, when a new Write command is issued, the previous burst will terminate and the new burst will
begin with a new Write command. WRITE will be interrupted by another WRITE.
The interval between the commands is minimum 1 cycle. Each Write command can be issued in every clock
without any restriction.

12. Burst Termination
There are two methods to terminate a burst operation other than using a Read or a Write command. One is the
burst stop command and the other is the precharge command.
12.1 Burst Stop Command
During a read cycle, when the burst stop command is issued, the burst read data are terminated and the data bus
goes to Hi-Z after the /CAS latency from the burst stop command.

12.2 Precharge Termination
12.2.1 Precharge Termination in READ Cycle
During a read cycle, the burst read operation is terminated by a precharge command.
When the precharge command is issued, the burst read operation is terminated and precharge starts.
The same bank can be activated again after tRP from the precharge command.
To issue a precharge command, tRAS must be satisfied.
When /CAS latency is 2, the read data will remain valid until one clock after the precharge command.

12.2.2 Precharge Termination in WRITE Cycle
During a write cycle, the burst write operation is terminated by a precharge command.
When the precharge command is issued, the burst write operation is terminated and precharge starts.
The same bank can be activated again after tRP from the precharge command.
To issue a precharge command, tRAS must be satisfied.
When /CAS latency is 2, the write data written prior to the precharge command will be correctly stored. However,
invalid data may be written at the same clock as the precharge command. To prevent this from happening, DQM
must be high at the same clock as the precharge command. This will mask the invalid data.

NOTES FOR CMOS DEVICES
1
PRECAUTION AGAINST ESD FOR SEMICONDUCTORS
Note:
Strong electric field, when exposed to a MOS device, can cause destruction of the gate oxide and
ultimately degrade the device operation. Steps must be taken to stop generation of static electricity
as much as possible, and quickly dissipate it once, when it has occurred. Environmental control
must be adequate. When it is dry, humidifier should be used. It is recommended to avoid using
insulators that easily build static electricity. Semiconductor devices must be stored and transported
in an anti-static container, static shielding bag or conductive material. All test and measurement
tools including work bench and floor should be grounded. The operator should be grounded using
wrist strap. Semiconductor devices must not be touched with bare hands. Similar precautions need
to be taken for PW boards with semiconductor devices on it.
2
HANDLING OF UNUSED INPUT PINS FOR CMOS
Note:
No connection for CMOS device inputs can be cause of malfunction. If no connection is provided
to the input pins, it is possible that an internal input level may be generated due to noise, etc., hence
causing malfunction. CMOS devices behave differently than Bipolar or NMOS devices. Input levels
of CMOS devices must be fixed high or low by using a pull-up or pull-down circuitry. Each unused
pin should be connected to VDD or GND with a resistor, if it is considered to have a possibility of
being an output pin. All handling related to the unused pins must be judged device by device and
related specifications governing the devices.
3
STATUS BEFORE INITIALIZATION OF MOS DEVICES
Note:
Power-on does not necessarily define initial status of MOS device. Production process of MOS
does not define the initial operation status of the device. Immediately after the power source is
turned ON, the devices with reset function have not yet been initialized. Hence, power-on does
not guarantee out-pin levels, I/O settings or contents of registers. Device is not initialized until the
reset signal is received. Reset operation must be executed immediately after power-on for devices
having reset function.
