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 4):
The semiconductor memory device according to  claim 3 , further comprising:\n a control circuit that determines the reading voltage and the comparative current before adjustment using the adjustment value are appropriate when the first comparison result indicates that the current flowing through the memory cell to be read is equal to or greater than the first comparative current, and the second comparison result indicates that the current flowing through the memory cell to be read is less than the second comparative current.
