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 B2 RAMs always transfer data in two packets, A0 is internally set to 0 for the first read or write transfer, and automatically incremented by 1 for the next transfer. Because the LSB is tied off internally, the address field of a SigmaQuad-II B2 RAM is always one address pin less than the advertised index depth (e.g., the 4M x 18 has a 2048K addressable index). SigmaQuad™ Family Overview The GSQ8662Q08/09/18/36E are built in compliance with the SigmaQuad-II SRAM pinout standard for Separate I/O synchronous SRAMs. They are 75,497,472-bit (72Mb) SRAMs. The GSQ8662Q08/09/18/36E SigmaQuad 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. Clocking and Addressing Schemes The GSQ8662Q08/09/18/36E 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 register clock inputs quasi independently with the C and Parameter Synopsis -300 tKHKH tKHQV 3.3 ns 0.45 ns -250 4.0 ns 0.45 ns -200 5.0 ns 0.45 ns -167 6.0 ns 0.5 ns Rev: 1.01 9/2005 1/35 © 2005, GSI Technology Specifications cited are subject to change without notice.
