Logical-to-physical mapping

Abstract:

A logical to physical (L2P) mapping component can determine whether an offset between a physical page address (PPA) and a logical block address (LBA) will be altered in response to writing data corresponding to the PPA and comprising at least one redundant array of independent NAND parity bit to a first level of a logical to physical (L2P) data structure or a second level of the L2P data structure, or both. The L2P mapping component can further cause an indication comprising at least two bits corresponding to the offset to be written to the first level of the L2P data structure or the second level of the L2P data structure, or both.
