Abstract :
This paper presents the design and evaluation of a sequential access memory (SAM) that provides low power and high performance by replacing address decoders with special locally-communicating sequencers. A test chip containing one 16×16-b SAM and one 64×16-b SAM (consisting of four 16×16-b banks) has been designed, fabricated, and evaluated using a 0.25-μm CMOS process. With a clock frequency of 40 MHz at 1.2 V, the measured worst-case read power dissipations for the 16×16-b SAM and the 64×16-b SAM are 344 μW and 358 μW respectively, demonstrating power dissipation that is largely independent of SAM size
