Patent number: 11784665Abstract: A memory system includes a non-volatile memory and a controller. The controller is configured to perform iterative correction on a plurality of frames of data read from the non-volatile memory. The iterative correction includes performing a first error correction on each of the frames including a first frame having errors not correctable by the first error correction, generating a syndrome on a set of second frames that include the first frame, performing a second error correction on the second frames using the syndrome, and performing a third error correction on the first frame. Each of the frames includes user data and first parity data used in the first error correction, the first parity data of the first frame also being used in the third error correction.Type: GrantFiled: October 28, 2022Date of Patent: October 10, 2023Assignee: Kioxia CorporationInventors: Yasuyuki Imaizumi, Satoshi Shoji, Mitsunori Tadokoro, Takashi Ishiguro, Yifan Tang
