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.
