Abstract
A stacked block array architecture.for a SRAM memory for low power applications. The architecture turns on only the required data cells and sensing circuitry to access a particular set of data cells of interest. The wordline delay is reduced by using a shorter and wider wordline wire size. Although less power is consumed, the performance is improved by the reduction in loading of wordlines and bitlines.
