128MB 32-bit Direct Rambus DRAM RIMM Module
MC-4R128FKK8K (32M words × 18 bits × 2 channels)
Description
Features
The 32-bit Direct Rambus RIMM module is a general-
purpose high-performance lines of memory modules
suitable for use in a broad range of applications
including computer memory, personal computers,
workstations, and other applications where high
bandwidth and latency are required.
• 128MB Direct RDRAM storage and 128 banks total
on module
• 2 independent Direct RDRAM channels, 1 pass
through and 1 terminated on 32-bit RIMM module
• High speed 800MHz Direct RDRAM devices
• 232 edge connector pads with 1mm pad spacing
Module PCB size: 133.35mm × 39.925mm ×
1.27mm
The 32-bit RIMM module consists of 288Mb Direct
Rambus DRAM (Direct RDRAM) devices. These are
extremely high-speed CMOS DRAMs organized as
16M words by 18 bits. The use of Rambus Signaling
Level (RSL) technology permits the use of conventional
system and board design technologies. The 32-bit
RIMM modules support 800MHz transfer rate per pin,
resulting in total module bandwidth of 3.2GB/s.
Gold plated edge connector pads contacts
• Serial Presence Detect (SPD) support
• Operates from a 2.5V (±5%) supply
• Low power and power down self refresh modes
• Separate Row and Column buses for higher
efficiency
The 32-bit RIMM module provides two independent 18
bit memory channels to facilitate compact system
design. The "Thru" Channel enters and exits the
module to support a connection to or from a controller,
memory slot, or termination. The "Term" Channel is
terminated on the module and supports a connection
from a controller or another memory slot.
The RDRAM
sustained bandwidth for multiple, simultaneous,
randomly addressed memory transactions. The
architecture enables the highest
separate control and data buses with independent row
and column control yield over 95% bus efficiency. The
RDRAM device multi-bank architecture supports up to
four simultaneous transactions per device.

If the RIMM module does not meet these specifications, then the specification can be adjusted by the
“Adjusted ∆TPD Specification” table.

Notes 1. Actual power will depend on individual RDRAM component specifications, memory controller and usage
patterns. Please refer to specific RIMM module vendor data sheets for additional information. Power does
not include Refresh Current. Max current computed for x16 256Mb RDRAM components. x18 288Mb
RDRAM components use 8 mA more current per RDRAM device in Read and 60mA more current per
RDRAM device in Write.
2. I/O current is a function of the % of 1’s, to add I/O power for 50 % 1’s for a x16 need to add 257mA or

CAUTION FOR HANDLING MEMORY MODULES
When handling or inserting memory modules, be sure not to touch any components on the modules, such as
the memory ICs, chip capacitors and chip resistors. It is necessary to avoid undue mechanical stress on
these components to prevent damaging them.
In particular, do not push module cover or drop the modules in order to protect from mechanical defects,
which would be electrical defects.
When re-packing memory modules, be sure the modules are not touching each other.
Modules in contact with other modules may cause excessive mechanical stress, which may damage the
modules.

NOTES FOR CMOS DEVICES
PRECAUTION AGAINST ESD FOR MOS DEVICES
1
Exposing the MOS devices to a strong electric field can cause destruction of the gate
oxide and ultimately degrade the MOS devices operation. Steps must be taken to stop
generation of static electricity as much as possible, and quickly dissipate it, when once
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. MOS 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. MOS devices must not be touched with bare hands. Similar precautions
need to be taken for PW boards with semiconductor MOS devices on it.
2
HANDLING OF UNUSED INPUT PINS FOR CMOS DEVICES
No connection for CMOS devices input pins can be a 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. The unused pins must be handled in accordance with the related specifications.
3
STATUS BEFORE INITIALIZATION OF MOS DEVICES
Power-on does not necessarily define initial status of MOS devices. Production process
of MOS does not define the initial operation status of the device. Immediately after the
power source is turned ON, the MOS devices with reset function have not yet been
initialized. Hence, power-on does not guarantee output pin levels, I/O settings or
contents of registers. MOS devices are not initialized until the reset signal is received.
Reset operation must be executed immediately after power-on for MOS devices having
reset function.
