Elpida Memory, Inc. is a joint venture DRAM company of NEC Corporation and Hitachi, Ltd.

Description

The Direct Rambus RIMM module is a general-purpose high-performance memory module subsystem suitable for

use in a broad range of applications including computer memory, personal computers, workstations, and other

applications where high bandwidth and low latency are required.

MC-4R64FKE6D modules consists of two 288M Direct Rambus DRAM (Direct RDRAM) devices (

PD488588).

These are extremely high-speed CMOS DRAMs organized as 16M words by 18 bits. The use of Rambus Signaling

Level (RSL) technology permits 600MHz, 711MHz or 800MHz transfer rates while using conventional system and

board design technologies.

Direct RDRAM devices are capable of sustained data transfers at 1.25 ns per two bytes (10 ns per sixteen bytes).

The architecture of the Direct RDRAM 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 Direct RDRAM's 32 banks support up to four simultaneous transactions

per device.

Features

184 edge connector pads with 1mm pad spacing

64 MB Direct RDRAM storage

Each RDRAM

has 32 banks, for 64 banks total on module

Gold plated contacts

RDRAMs use Chip Scale Package (CSP)

Serial Presence Detect support

Operates from a 2.5 V supply

Powerdown self refresh modes

Separate Row and Column buses for higher efficiency

Over Drive Factor (ODF) support
