Burst of 2 SRAM

450 MHz–300 MHz

1.8 V V

1.8 V or 1.5 V I/O

The GS8342T07/10/19/37BD SigmaDDR-II+ 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 GS8342T07/10/19/37BD SigmaDDR-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 SigmaDDR-II+ B2

RAM is two 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

SigmaDDR-II+ B2 RAM is always one address pin less than

the advertised index depth (e.g., the 4M x 8 has a 2M

addressable index).

SigmaDDR™ Family Overview

The GS8342T07/10/19/37BD are built in compliance with the

SigmaDDR-II+ SRAM pinout standard for Common I/O

synchronous SRAMs. They are 37,748,736 (36Mb) SRAMs.
