Abstract
An 8 Mb CMOS SRAM cycles at 470 MHz and provides a data rate of 940 MHz when run in the double-data rate (DDR) mode. Improved redundancy minimizes SRAM latency, enabling 3.4 ns access time. The HSTL I/O performance is enhanced by using flip-chip C4 packaging and by decoupling the I/O supply on-chip. The 8 Mb SRAM has an architecture to allow both /spl times/18 and /spl times/36 organizations, as well as a 4 Mb cut-down.
