Abstract:
A semiconductor memory device and a data reading method capable of appropriately reading data stored in memory cells are provided. The semiconductor memory device includes: a memory cell array including multiple memory cells and having a known-data storage area storing determination data used for determining appropriateness or inappropriateness of a value of each of a reading voltage applied to a memory cell when reading data stored in the memory cell and a comparative current used for a comparison with a current flowing through a memory cell according to stored data; a decoder that applies the reading voltage to a memory cell to be read according to an address representing the memory cell to be read; and a sense amplifier including a comparison circuit that outputs a comparison result acquired by comparing a current flowing through the memory cell to be read 66 according to stored data with the comparative current.

Claim (Index 3):
The semiconductor memory device according to  claim 2 ,\n wherein the determination data includes first data and second data having different logic values, and a current flowing through a memory cell in which the first data is stored is higher than a current flowing through a memory cell in which the second data is stored, wherein the comparative current generating circuit outputs a first comparative current increased based on the adjustment value to the comparison circuit as the comparative current when the memory cell to be read is a memory cell in which the first data is stored and outputs a second comparative current decreased based on the adjustment value to the comparison circuit as the comparative current when the memory cell to be read is a memory cell in which the second data is stored, and wherein the comparison circuit outputs a first comparison result acquired by comparing the first comparative current with the current flowing through the memory cell to be read when the memory cell to be read is a memory cell in which the first data is stored and outputs a second comparison result acquired by comparing the second comparative current with the current flowing through the memory cell to be read when the memory cell to be read is a memory cell in which the second data is stored.
