Abstract:
In some implementations, a built-in self-test (BIST) circuitry of a memory device is configured to perform an execution of a test sequence to test the memory device, wherein performing the execution comprises generating addresses of the memory device in accordance with the test sequence and advancing a value of a modulo counter as each of the addresses is generated, enable error logging when a generated address and a value of the modulo counter corresponding to the generated address match an address and a value of the modulo counter stored for a previously detected error, detect an error in data read from the memory device after enabling error logging, and store information associated with the detected error.
