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 2 Read and Write

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

• 1.5 V or 1.8 V HSTL Interface

The GSQ8662Q08/09/18/36E 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 9Mb, 18Mb, and 36Mb and

future 144Mb devices

Each internal read and write operation in a SigmaQuad-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

SigmaQuad-II B2 RAM is always one address pin less than the

advertised index depth (e.g., the 8M x 8 has an 4M addressable

index).

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

• RoHS-compliant 165-bump BGA package available

SigmaQuad™ Family Overview

The GSQ8662Q08/09/18/36E are built in compliance with

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

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

SRAMs. The GSQ8662Q08/09/18/36E 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.
