SigmaRAM™ Family Overview
GS8180QV18/36B are built in compliance with the SigmaQuad SRAM pinout standard for Separate I/O synchronous SRAMs. They are18,874,368-bit (18Mb) SRAMs. These are the first in a family of wide, very low voltage HSTL I/O SRAMs designed to operate at the speeds needed to implement economical high performance networking systems.
family of SigmaRAMs, the SigmaQuad family of SRAMs allows a user to implement the interface protocol best suited to the task at hand.
Clocking and Addressing Schemes
A Burst of 2 SigmaQuad SRAM is a synchronous device. It employs 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 ma...
