Abstract:
A memory cell array is configured to have a plurality of memory cells arranged in a matrix, each of the memory cells being connected to a word line and a bit line and being capable of storing n values (n is a natural number equal to or larger than 3). A control circuit controls the potentials of the word line and bit line according to input data and writes data into a memory cell. The control circuit writes data into the memory cell to a k-valued threshold voltage (k<=n) in a write operation, precharges the bit line once, and then changes the potential of the word line an i number of times to verify whether the memory cell has reached an i-valued (i<=k) threshold voltage.

Claim (Index 1):
A semiconductor memory device comprising:\n a memory cell array configured to have a plurality of memory cells arranged in a matrix, each of said plurality of memory cells being connected to a word line and a bit line and being capable of storing n values (n is a natural number equal to or larger than 3); and a control circuit which controls the potentials of the word line and bit line according to input data and writes data into a memory cell, wherein the control circuit writes data into the memory cell to an a1-valued (a1\u2264n) threshold voltage in a first write operation, to an a2-valued (a2\u2264n) threshold voltage in a second write operation, and to an ak-valued (ak\u2264n) threshold voltage in a k-th write operation (k is a natural number equal to or larger than 2: k\u2264n), in the first to k-th write operations, raises a program voltage in increments of \u0394Vpgm, and carries out write operations by repeating a program and verify operation, \u0394Vpgm in the first to k-th write operations fulfilling the following expression: \u0394Vpgm in the first write operation>\u0394Vpgm in the second write operation> . . . >\u0394Vpgm in the kth write operation.
