Systems and methods for providing non-power-of-two flash cell mapping

摘要

Systems, methods, and computer programs are disclosed for providing compressed data storage using non-power-of-two flash cell mapping. One embodiment of a method comprises receiving one or more compressed logical pages to be stored in a NAND flash memory. Binary data in the one or more logical pages is transformed to a quinary representation. The quinary representation comprises a plurality of quinary bits. A binary representation of each of the plurality of quinary bits is transmitted to the NAND flash memory. The binary representation of each of the plurality of quinary bits is converted to a quinary voltage for a corresponding cell in a physical page in the NAND flash memory.

1. A method for providing compressed data storage using non-power-of-two flash cell mapping, the method comprising:
receiving one or more compressed logical pages to be stored in a NAND flash memory; transforming binary data in the one or more logical pages to a quinary representation, the quinary representation comprising a plurality of quinary bits; transmitting a binary representation of each of the plurality of quinary bits to the NAND flash memory; and converting the binary representation of each of the plurality of quinary bits to a quinary voltage for a corresponding cell in a physical page in the NAND flash memory.
