Abstract: A built-in programmable self-diagnostic circuit for finding and locating faults in a static random access memory (SRAM) unit. The circuit includes a plurality of multiplexers, a demultiplexer, a test pattern generator, a fault location indicator and a controller. The circuit uses either internal test instructions or pre-programmed test instructions to test the SRAM unit so that the exact location of any fault in the SRAM unit can be found and subsequently repaired.
