If the C clocks are tied high, the K clocks are routed internally to fire the output registers instead. Sigma CIO™ Family Overview The GS8342T08/09/18/36E are built in pliance with the Sigma CIO DDR-II SRAM pinout standard for mon I/O synchronous SRAMs. They are 37,748,736-bit (36Mb) SRAMs. The GS8342T08/09/18/36E Sigma CIO 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. http://..net/ Clocking and Addressing Schemes The GS8342T08/09/18/36E Sigma CIO DDR-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 register clock inputs quasi independently with the C and C clock inputs. C and C are also independent single-ended mon I/O x36 and x18 Sigma CIO DDR-II...
