Abstract

An apparatus and method for correcting corrupted data. Access logic accesses a memory. Error detection logic generates an error signal for each data value output by the memory to indicate whether the data value has a correctable error. Correction logic requests the access logic to write to the memory a corrected version of each data value indicated by the error signal to have a correctable error.
