Abstract:
According to one embodiment, a semiconductor memory device includes a memory cell array, a data storage circuit and a control circuit. The data storage circuit holds first data to be written into the memory cell and holds 1 bit data calculated from the first data. The control circuit writes the data of n bits into the memory cell in a first write operation and then executes a second write operation. The control circuit carries out the following control in the second write operation. It reads data stored in the memory cell in the first write operation. It restores the first data based on the data read from the memory cell and the 1 bit data held in the data storage circuit. It writes the restored first data into the memory cell.

Claim (Index 16):
A semiconductor memory device comprising:\n a first memory cell configured to store k bits (n=2 k ) by a first state, a second state, . . . n state (n is a natural number); and a data storage circuit electrically connected to the first memory cell and configured to hold a write data to the first memory cell, wherein a state of the first memory cell is written from the first state to one of the first state, the second state, . . . the n state depending on data of k bits after the data of k bits is inputted to the data storage circuit in a first write operation, data of h bits (h<k) generated by the data of k bits is inputted to the data storage circuit in a second write operation, and data is read from the first memory cell written by the first write operation, the data of k bits is restored by a read data and the data of h bits and a write operation is executed to the first memory cell once again by data of restored k bits.
