SigmaRAM Family Overview

GS8170DW36/72 SigmaRAMs are built in compliance with

the SigmaRAM pinout standard for synchronous SRAMs.

They are 18,874,368-bit (18Mb) SRAMs. This family of wide,

very low voltage CMOS I/O SRAMs is designed to operate at

the speeds needed to implement economical high performance

networking systems.

Because SigmaRAMs are synchronous devices, address data

inputs and read/write control inputs are captured on the rising

edge of the input clock. Write cycles are internally self-timed

and initiated by the rising edge of the clock input. This feature

eliminates complex off-chip write pulse generation required by

asynchronous SRAMs and simplifies input signal timing.

RAMs support pipelined reads utilizing a rising-edge-

triggered output register. They also utilize a Dual Cycle

Deselect (DCD) output deselect protocol.

RAMs are offered in a number of configurations including

Late Write, Double Late Write, and Double Data Rate (DDR).

The logical differences between the protocols employed by

these RAMs mainly involve various approaches to write

cueing and data transfer rates. The

RAM

™

family standard

allows a user to implement the interface protocol best suited to

the task at hand.

RAMs are implemented with high performance CMOS

technology and are packaged in a 209-bump BGA.
