Clocking and Addressing Schemes The GS8342Q07/10/19/37BD 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+ B2 RAM is two times wider than the device I/O bus. An input data bus de-multiplexer is used to accumulate ining data before it is simultaneously written to the memory array. An output data multiplexer is...
