INCREMENTAL ERROR DETECTION AND CORRECTION FOR MEMORIES

摘要

A device and method for incrementally updating the error detecting and correcting bits for an error corrected block of data in a cross point memory array is disclosed. When an error corrected block of data is modified, only the modified data bits and the incrementally updated error detecting and correcting bits are changed in the cross point memory device for improved performant and reduced impact to device endurance.

1. A method of storing information in an electronic memory device having one or more pluralities of bits whereby a plurality of bits consists of data bits and error detecting and/or error correcting bits, comprising the steps of:
(i) changing fewer than the total number of data bits; (ii) determining a change to the error detecting and/or error correcting bits corresponding to the change in data bits; (iii) writing data bits to the memory device; and (iv) writing error correcting bits to the memory device.
