Abstract
A memory cell array unit according to an embodiment of the present disclosure includes a microcontroller that performs reading and writing from and into a memory cell array using n-bit allocation memory cells on the basis of read/write control from a memory controller. When a defect is found in one of the n-bit allocation memory cells, the microcontroller writes n−1-bit write data excluding data of a least significant bit among n-bit write data into n−1-bit allocation memory cells excluding the defective allocation memory cell among the n-bit allocation memory cells.
