Memory error recovery using shared structural element error correlations

Abstract:

A determination is made that bit errors of a selected data chunk stored in a computer memory are unable to be completely corrected using an initial error correction scheme. A plurality of other data chunks sharing a physical layout structure element of the computer memory with the selected data chunk is analyzed to identify one or more likely bit error locations of the selected data chunk aligned with one or more corresponding bit error locations of a threshold number of the analyzed other data chunks. An attempt is made to correct the bit errors of the selected data chunk based on the identified one or more likely bit error locations of the selected data chunk.
