Cluster based non-volatile memory translation layer

A system comprising:

• a host coupled to a non-volatile memory device, wherein the system is adapted to store logical blocks of data in the non-volatile memory device, where the logical blocks are grouped in a plurality of clusters, each cluster containing an adjustable number of sequentially addressed logical blocks.

A method of operating a non-volatile memory comprising:

• accessing logical blocks in a non-volatile memory by reference to a logical cluster address, wherein each cluster contains an adjustable number of sequentially addressed logical blocks.

A method of translating a logical block address to a physical address in a non-volatile memory comprising:

• scanning a non-volatile memory on a physical cluster address basis to locate a logical cluster address containing a matching logical block address, wherein each cluster of the non-volatile memory contains an adjustable number of sequentially addressed logical blocks;
• and
• determining the physical block address offset for the logical block address within the physical cluster corresponding to the logical cluster address containing the matching logical block address.
