SigmaDDR™ Family Overview
The GS81302R08/09/18/36E are built in compliance with the SigmaDDR-II SRAM pinout standard for Common I/O synchronous SRAMs. They are 150,994,944-bit (144Mb) SRAMs. The GS81302R08/09/18/36E 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 GS81302R08/09/18/36E 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 ...
