Abstract:
A method for storing information in SRAM bit cell arrays provides for lowering voltage supplied to the SRAM bit cell arrays, with voltage lowering controlled by a connected voltage control circuit. Writing, reading, and correcting information storable in the SRAM bit cell arrays is accomplished using an error correcting code (ECC) block connected to at least some of the SRAM bit cell arrays. The ECC block is configurable to repair stored information.
