ABSTRACT:
A resistance change memory device includes: a memory cell array with memory cells arranged therein, the memory cell having a variable resistance element for storing a rewritable resistance value; a reference cell formed of the same memory cells as those set in a high resistance state in the memory cell array, the reference cell being trimmed with selection of the number of parallel-connected memory cells to have a reference current value used for detecting data in the memory cell array; and a sense amplifier configured to compare a cell current value of a memory cell selected in the memory cell array with the reference current value of the reference cell.
