SigmaQuad™ Family Overview
The GSQ8342Q08/09/18/36E are built in compliance with the SigmaQuad-II SRAM pinout standard for Separate I/O synchronous SRAMs. They are 37,748,736-bit (36Mb) SRAMs. The GSQ8342Q08/09/18/36E 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.
Clocking and Addressing Schemes
The GSQ8342Q08/09/18/36E 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 ...
