SRAMs. The GS8662D06/11/20/38BD 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 GS8662D06/11/20/38BD 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.

Each internal read and write operation in a SigmaQuad-II+ B4

RAM is four times wider than the device I/O bus. An input

data bus de-multiplexer is used to accumulate incoming data

before it is simultaneously written to the memory array. An

output data multiplexer is used to capture the data produced

from a single memory array read and then route it to the

appropriate output drivers as needed. Therefore 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 8 has a 2M

addressable index).

SigmaQuad-II™ Family Overview

The GS8662D06/11/20/38BD are built in compliance with

the SigmaQuad-II+ SRAM pinout standard for Separate I/O

synchronous SRAMs. They are 75,497,472-bit (72Mb)
