Data encoding for non-volatile memory

摘要

A data storage device includes a memory device and a controller. Mapping circuitry is configured, in response to receiving data, to apply a one-to-many mapping to each group of multiple groups of bits in the received data to generate mapped data that includes multiple groups of mapped bits. Storage elements of the memory device are partitioned into multiple skip groups and the mapped bits of each group of mapped bits are interleaved across the skip groups such that different bits of a group of mapped bits are written into different skip groups.

1. A device comprising:
a controller; a memory device coupled to the controller and configured to write data to storage elements partitioned into multiple skip groups; and mapping circuitry configured, in response to receiving data to be stored into the storage elements, to apply a one-to-many mapping to each group of multiple groups of bits in the received data to generate mapped data that includes multiple groups of mapped bits, wherein the mapped data differs from the received data, and wherein the mapped bits of each of the groups of mapped bits are interleaved across the skip groups such that different bits of at least one of the groups of mapped bits are written into different skip groups.
