576 Kilobyte Synchronous Card Edge DIMM

FEATURES

•

4x64Kx18 Synchronous

Flow-Through Architecture

The EDI2KG41864VxxD2 is a Synchronous SRAM, 60 position

Card Edge DIMM (120 contacts) Module, organized as 4x64Kx18.

The Module contains four (4) Synchronous Burst Ram Devices,

packaged in the industry standard JEDEC 14mmx20mm TQFP

placed on a Multilayer FR4 Substrate. The module architecture is

defined as a Synchronous Only, Flow-Through, Early Write device.

This module provides high performance, ultra fast access times at a

cost per bit benefit over BiCMOS Asynchronous SRAM based

devices. As well as improved cost per bit, the use of Synchronous

or Synchronous Burst devices or modules can ease the memory

subsystem design by reducing or easing the memory controller

requirement.

Access Speed(s): TKHQV=9.5, 10, 11, 12, 15ns

Common Data I/O

Synchronous operations are in relation to an externally supplied clock,

registered address, registered global write, registered enables as well

as an Asynchronous Output enable. All read and Write operations to

this module are performed on Long Words (Double Words) 32 bit

operation.

High Capacitance (30pf) drive, at rated Access

Speed

•

Single total array Clock

Multiple Vcc and Gnd

Write cycles are internally self timed and are initiated by a rising clock

edge. This feature relieves the designer the task of developing external

write pulse width circuitry.
