Abstract
A 4-kb SRAM design is presented with functionality of 12 MHz at a supply voltage of 0.9 V with an r.m.s. run power (1 MHz) of 18 μW. The circuit operates at maximum frequency of 40 MHz at a supply voltage of 1.6 V with an rms run power (1 MHz) of 64 μW. The design utilizes a subblocked array architecture as well as selective use of NOR/NAND-based decode logic. The sense amplifier design is a low voltage, glitch-free design to conserve power
