Abstract
According to one embodiment, a memory controller includes a compression unit that compresses two or more determination voltage values for threshold voltages of a memory cell to a vector quantity, the memory cell being capable of storing three or more data values. The memory controller further includes a storing unit that stores the vector quantity into a memory region. The memory controller further includes a decompression unit that decompresses the stored vector quantity to provide the determination voltage values.
