Abstract
A 16-Mb CMOS SRAM using 0.4-mum CMOS technology has been developed. Th
is SRAM features common-centroid-geometry (CCG) layout sense amplifier
s which shorten the access time by 2.4 ns. A flexible redundancy techn
ique achieves high efficiency without any access penalty. A memory cel
l with stacked capacitors is fabricated for high soft-error immunity.
A 16-Mb SRAM with a chip size of 215 mm2 is fabricated and an address
access time of 12.5 ns has been achieved.
