Abstract
According to one embodiment, a processor system includes a variable capacity memory. The memory includes a memory cell array including basic units, each of the basic units including one cell transistor and one variable resistance element, a mode selector switching between first and second modes, a read/write of one bit executed in 2basic units (n is an integer) among the basic units in the first mode, the read/write of the one bit executed in 2basic units (m is an integer, m≠n) among the basic units in the second mode, and a control circuit which controls the switching between the first and second modes.
