Abstract

Error detection circuitry is configured to receive raw read data from a memory, perform error detection in accordance with a single-bit error correction and double-bit error detection (SECDEC) error-correction code (ECC) on the raw read data, and provide a single bit correction indicator in response to performing the SECDEC ECC on the raw read data. Error correction circuitry is configured to provide corrected read data corresponding to the raw read data based at least on the single bit correction indicator. ECC checking circuitry is configured to generate a wrong operation indicator based at least on a parity of the raw read data, a parity of the corrected read data, and the single bit correction indicator, wherein the ECC checking circuitry is configured to assert the wrong operation indicator when at least one of the error detection circuitry or the error correction circuitry is not operating correctly.
