Abstract: Various additional and alternative aspects are described herein. In some aspects, the present disclosure provides a method of testing error-correcting code (ECC) logic. The method includes receiving data for storage in a memory. The method further includes receiving an address indicating a location in the memory to store the data. The method further includes determining if the received address matches at least one of one or more test addresses. The method further includes operating the ECC logic in a normal mode when the received address does not match at least one of the one or more test addresses. The method further includes operating the ECC logic in a test mode when the received address does match at least one of the one or more test addresses.

Abstract: A system and a method for error-correction code (“ECC”) error handling is described herein. In one aspect, the system and method may operate an ECC function on raw data. The ECC function may include generating ECC syndrome data by an ECC syndrome data generating module. The ECC syndrome data may be derived from the raw data. The system and a method may further inject a fault based on the ECC syndrome data or the raw data. The system and a method may further determine whether the ECC error detected by the ECC checker corresponds to a malfunction of the ECC function or the fault injected based on the ECC syndrome data or the raw data.
