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 10):
A method for reading data in a semiconductor memory device comprising: a memory cell array comprising a plurality of memory cells and having a known-data storage area in which determination data used for determining appropriateness or inappropriateness of a value of each of a reading voltage applied to a memory cell at the time of reading data stored in the memory cell and a comparative current used for a comparison with a current flowing through a memory cell in accordance with the stored data is stored; a decoder applying the reading voltage to a memory cell in accordance with an address representing the memory cell from which data is to be read; and a comparison circuit that outputs a comparison result acquired by comparing a current flowing through the memory cell in accordance with the stored data with the comparative current, the data reading method comprising:\n performing the determination of the appropriateness or inappropriateness based on the comparison result at the time of reading the determination data; setting the reading voltage determined to be appropriate as a reading voltage to be applied by the decoder; and setting the comparative current determined to be appropriate as a comparative current to be compared by the comparison circuit.
