Publication number: 20220206892Abstract: A memory system includes a non-volatile memory including at least one memory cell, a buffer, and a memory controller. The memory controller acquires first data from the buffer. The first data includes a plurality of bits of data. The memory controller generates second data by performing a randomization process on the first data, generates a flag that is information used to identify an error suppression encoding process, based on the second data, and stores the flag in the buffer. The memory controller acquires third data and the flag from the buffer. The third data is 1-bit data of the first data. The memory controller generates storage data by performing the error suppression encoding process based on the acquired flag and the randomization process on the third data, and writes the storage data into the memory cell.Type: ApplicationFiled: July 2, 2021Publication date: June 30, 2022Applicant: Kioxia CorporationInventors: Yasuyuki IMAIZUMI, Tokumasa HARA, Toshiyuki YAMAGISHI
