Abstract
In one embodiment, memory circuitry includes an error-correction code (ECC) encoder, memory, and an ECC decoder. The ECC encoder performs encoding, based on an ECC algorithm having an algorithm size, on an algorithm-size segment of input user data to generate a corresponding subset of parity data for the segment of input user data. The memory has input user data and corresponding parity data written based on a write data size and stored user data and corresponding stored parity data read based on a read data size. The ECC decoder performs decoding, based on the ECC algorithm, on an algorithm-size segment of retrieved user data and a corresponding subset of retrieved parity data, wherein the algorithm size is smaller than the write data size or the read data size. The memory circuitry enables conventional SEC-DED algorithms to be used when the write and read data sizes are different.
