72Mb SigmaDDR-II^TM

Burst of 2 SRAM

1.8 V V

1.8 V and 1.5 V I/O

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.

Features

• Simultaneous Read and Write SigmaDDR™ Interface

• Common I/O bus

• JEDEC-standard pinout and package

• Double Data Rate interface

• Byte Write (x36, x18 and x9) and Nybble Write (x8) function

• Burst of 2 Read and Write

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

• 1.5 V or 1.8 V HSTL Interface

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.

• Pipelined read operation with self-timed Late Write

• 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, 36Mb and 72Mb

devices

• 165-bump, 13 mm x 15 mm, 1 mm bump pitch BGA package

• RoHS-compliant 165-bump BGA package available

When a new address is loaded into a x18 or x36 version of the

part, A0 is used to initialize the pointers that control the data

multiplexer / de-multiplexer so the RAM can perform "critical

word first" operations. From an external address point of view,

regardless of the starting point, the data transfers always follow

the same sequence {0, 1} or {1, 0} (where the digits shown

represent A0).

SigmaDDR™ Family Overview

The GS8662T08/09/18/36BD are built in compliance with the

SigmaDDR-II SRAM pinout standard for Common I/O

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

SRAMs. The GS8662T08/09/18/36BD 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.

Unlike the x18 and x36 versions, the input and output data

multiplexers of the x8 and x9 versions are not preset by

address inputs and therefore do not allow "critical word first"

operations. The address fields of the x8 and x9 SigmaDDR-II

B2 RAMs are one address pin less than the advertised index

depth (e.g., the 8M x 8 has an 4M addressable index, and A0 is

not an accessible address pin).

Clocking and Addressing Schemes

The GS8662T08/09/18/36BD SigmaDDR-II SRAMs are

synchronous devices. They employ two input register clock

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