Abstract

The present invention relates to a method for improving speed and increasing performance in a multi-port register file memory or SRAM including at least one storage element and other circuitry that operate synchronously or asynchronously. The method comprises differentially sensing a small voltage swing in the multi-port memory using a two-stage analog-style sense amplifier including at least one trip-level-shifted inverter device.
