PRELIMINARY DATA SHEET 256MB 32-bit Direct Rambus DRAM RIMM Module MC-4R256FKK8K (64M words x 18 bits x 2 channels) Description The 32-bit Direct Rambus RIMM module is a generalpurpose 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. 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. 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 architecture enables the highest sustained bandwidth for multiple, simultaneous, randomly addressed memory transactions. The 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. Features * 256MB Direct RDRAM storage and 256 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 x 39.925mm x 1.27mm 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 Document No. E0253N10 (Ver. 1.0) Date Published April 2002 (K) Japan URL: http://www.elpida.com Elpida Memory, Inc. 2002 Elpida Memory, Inc. is a joint venture DRAM company of NEC Corporation and Hitachi, Ltd.

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. MDE0202 NOTES FOR CMOS DEVICES 1 PRECAUTION AGAINST ESD FOR MOS DEVICES 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.
