C and C are also independent single-ended clock inputs, not differential inputs. If the C clocks are tied high, the K clocks are routed internally to fire the output registers instead. Because Separate I/O SigmaQuad-II B4 RAMs always transfer data in four packets, A0 and A1 are internally set to 0 for the first read or write transfer, and automatically incremented by 1 for the next transfers. Because the LSBs are tied off internally, the address field of a SigmaQuad-II B4 RAM is always two address pins less than the advertised index depth (e.g., the 2M x 18 has a 512K addressable index)...
