A 12.5-ns 16-Mb CMOS SRAM with common-centroid-geometry-layout sense amplifiers

A 16-Mb CMOS SRAM using 0.4-/spl mu/m CMOS technology has been developed. This SRAM features common-centroid-geometry (CCG) layout sense amplifiers which shorten the access time by 2.4 ns. A flexible redundancy technique achieves high efficiency without any access penalty. A memory cell with stacked...

description A 16-Mb CMOS SRAM using 0.4-/spl mu/m CMOS technology has been developed. This SRAM features common-centroid-geometry (CCG) layout sense amplifiers which shorten the access time by 2.4 ns. A flexible redundancy technique achieves high efficiency without any access penalty. A memory cell with stacked capacitors is fabricated for high soft-error immunity. A 16-Mb SRAM with a chip size of 215 mm/sup 2/ is fabricated and an address access time of 12.5 ns has been achieved.< >
