ABSTRACT:
An apparatus comprises a memory with a matrix (10) with rows and columns of memory cells. A read access circuit (14, 16, 18) executes a read command to read a retrieval unit comprising data from a row of the memory cells from the matrix (10) and to output data from the retrieval unit. A processing circuit (12) coupled to the read access circuit (14, 16, 18) is configured to execute an extra read operation involving issuing the read command, receiving the extra data (24), performing error detection on only the extra data (24), using an error detecting code in which the extra data is coded, conditionally performing error correction on the data from the extra data (24) using data from the retrieval unit including the payload data (22), according to an error correcting code in which the retrieval unit is coded, if the error detection indicates an error in the extra data (24). The processing circuit (12) performs further processing using the data from the extra data (22) or the corrected extra data, dependent on whether the error detection indicates an error in the extra data (22).
