Abstract
A memory cell array unit according to an embodiment of the present disclosure includes a memory cell array and a microcontroller. The memory cell array includes an n-bit allocation bit allocated from a memory controller in read/write control, and a redundant bit of one or a plurality of bits not being provided with a switching mechanism that switches as a substitution for a portion of the allocation bit. The microcontroller reads and writes n-bit data from and into the memory cell array using the allocation bit and the redundant bit on the basis of the read/write control from the memory controller.
