SigmaQuad™ Family Overview

The GS81302D08/09/18/36E are built in compliance with the

SigmaQuad-II SRAM pinout standard for Separate I/O

synchronous SRAMs. They are 150,994,944-bit (72Mb)

SRAMs. The GS81302D08/09/18/36E SigmaQuad SRAMs

are just one element in a family of low power, low voltage

HSTL I/O SRAMs designed to operate at the speeds needed to

implement economical high performance networking systems.

Clocking and Addressing Schemes

The GS81302D08/09/18/36E SigmaQuad-II SRAMs are

synchronous devices. They employ two input register clock

inputs, K and K. K and K are independent single-ended clock

inputs, not differential inputs to a single differential clock input

buffer.

Burst of 4 SRAM

Because Separate I/O SigmaQuad-II B4 RAMs always transfer

data in four packets, A0 and A1 are internally set to 0 for the

first read or write transfer, and automatically incremented by 1

for the next transfers. Because the LSBs are tied off internally,

the address field of a SigmaQuad-II B4 RAM is always two

address pins less than the advertised index depth (e.g., the 8M

x 18 has a 2M addressable index).
