Abstract
A memory controller determines the number of pieces of correction information of an a-th correction information for each of M component codes according to a value based on the number of component codes, and determines a correction information address which is an address on a correction information memory of the a-th correction information based on the number of pieces of correction information. The memory controller calculates an a-th soft-input value for an a-th component code, inputting the a-th soft-input value to execute decoding processing of the a-th component code, calculates a decoded word of the a-th component code, a-th correction information, and a-th reliability information, stores the a-th correction information and b-th correction information indicating a b-th corrected location (1≤b≤nj) in a j-th dimension (j≠i, 1≤j≤N) in the correction information address of the correction information memory, stores a-th reliability information in a reliability information memory, and outputs an output decoded word calculated from the read information and the reliability information of each component code.
