Clocking and Addressing Schemes The GS8342Q08/09/18/36BD 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 the user to manipulate the output regist...
