Abstract:
Storage device programming methods, systems and media are described. A method may include encoding data to generate an encoded set of data. A first programming operation may write the encoded set of data to a memory device. The method includes encoding, using a second encoding operation based on the data, to generate a second set of encoded data. The second set of encoded data is stored to a cache. A first decoding operation is performed, based on the second set of encoded data and the encoded set of data, to generate a decoded set of data. A second decoding operation is performed to generate a second decoded set of data. The second decoded set of data is encoded to generate a third set of encoded data. The method includes performing a second programming operation to write the third set of encoded data to the memory device.
