Testing for memory error correction code logic

Abstract:

Systems and methods disclosed herein provide for improved testing of memory error correction code ("ECC") logic with memory built-in self-test ("MBIST"). Embodiments provide for a masking element to inject one or more faults into the ECC logic during at least one of a manufacturing test ("MFGT") and a power-on-self-test ("POST"), wherein, based on the injected faults, it can be determined if the ECC logic contains any errors.
