Features

Clocking and Addressing Schemes

• Simultaneous Read and Write SigmaQuad™ Interface

• JEDEC-standard pinout and package

• Dual Double Data Rate interface

• Byte Write controls sampled at data-in time

• Burst of 4 Read and Write

• 1.8 V +100/–100 mV core power supply

• 1.5 V or 1.8 V HSTL Interface

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. The device also allows the user to manipulate the

output register clock inputs quasi independently with the C and

C clock inputs. C and C are also independent single-ended

clock inputs, not differential inputs. If the C clocks are tied

high, the K clocks are routed internally to fire the output

registers instead.

• Pipelined read operation

• Fully coherent read and write pipelines

• ZQ pin for programmable output drive strength

• IEEE 1149.1 JTAG-compliant Boundary Scan

• Pin-compatible with present 144 Mb devices

• 165-bump, 15 mm x 17 mm, 1 mm bump pitch BGA package

• RoHS-compliant 165-bump BGA package available

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 16M x 8 has a

4M addressable index).

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 (144Mb)

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.
