Abstract
An apparatus comprises a storage configured to store data items associated with error correction codes (ECCs); data retrieval circuitry responsive to a data retrieval request specifying a retrieval address to retrieve a retrieved data item and an associated ECC from a storage location corresponding to the retrieval address; and ECC decoding circuitry to generate a syndrome value by performing an ECC decoding operation on a decoding input value comprising data bits of the retrieved data item, code bits of the associated ECC, and address bits of the retrieval address, and to determine based on the syndrome value whether an error condition has occurred. Each bit of the syndrome value depends on a different combination of bits of the decoding input value. For each data bit of the decoding input value, an odd number of bits of the syndrome value depend on that data bit. For each address bit of the decoding input value, an even number of bits of the syndrome value depend on that address bit.
