Abstract

An SRAM memory cell (10) is provided a boosted voltage by a charge pump (56) to reduce the soft error rate within the SRAM (10) and to improve bit cell stability. A voltage regulator (58) is coupled to the charge pump (56) to regulate the operation of the charge pump (56) and its outputted boosted voltage. The voltage regulator (58) regulates the boosted voltage over three operating states: low supply voltage, steady state operation, and burn-in.
