A semiconductor integrated circuit device includes a cell array having a plurality of memory cells, a peripheral circuit which controls the cell array, and an operation information determination circuit. The operation information determination circuit determines either of a first operation mode in which one bit is stored by using one memory cell and a second operation mode in which one bit is stored by using two semiconductor memory cells, and supplies operation information to the peripheral circuit. The operation information determines which of the first and second operation modes is used to operate the cell array.
