EDI2GG418128V

4x128Kx18, 3.3V Synchronous Flow-Through SRAM CARD EDGE DIMM

FEATURES

■ 4x128Kx18 Synchronous

The EDI2GG418128VxxD2 is a Synchronous SRAM, 60 position

Card Edge; DIMM (120 contacts) module, organized as 4x128Kx64.

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 De-

vice. 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

■ Flow-Through Architecture

■ Clock Controlled Registered Bank Enables (E1\, E2\,E3\,E4\)

■ Clock Controlled Registered Address

■ Clock Controlled Registered Global Write (GW\)

■ Aysnchronous Output Enable (G\)

■ Internally self-timed Write

■ Gold Lead Finish

■ 3.3V ±10%, -5% Operation

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.

■ Common Data I/O

■ High Capacitance (30pF) drive, at rated Access Speed

■ Single total array Clock

■ Multiple Vcc and Vss

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

clock edge. This feature relieves the designer the task of devel-

oping external write pulse width circuitry.
