Title: Memory system
Inventor: KIBUNE NAOKO
IPC: H03M13/29
Filed: 2018-09-18
Abstract: To enable the performance of error correction with higher accuracy.SOLUTION: According to one embodiment, a memory system includes a nonvolatile memory and a memory controller. The nonvolatile memory stores an N-dimensional (N is an integer of 2 or more) error correction code. The memory controller performs a first decoding process for an n-dimensional component of the N-dimensional error correction code read from the nonvolatile memory. If the decoding of the error correction code by an m-th decoding process for the n-dimensional component fails, an (m + 1)-th decoding process is performed for the n-dimensional component. After the m-th decoding process is completed, bits that are not corrected by decoding with components other than the n-dimensional component but that are corrected by decoding with the n-dimensional component are changed to corresponding bits out of input data of the m-th decoding process. Using the changed data, the (m + 1)-th decoding process is executed for the n-dimensional component.SELECTED DRAWING: Figure 1
