Clocking and Addressing Schemes The GS82582D20/38GE 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. Each internal read and write operation in a SigmaQuad-II...
