Abstract
During data reading, a sense enable signal is activated to start charging of a data line prior to formation of a current path including the data line and a selected memory cell in accordance with row and column selecting operations. Charging of the data line is completed early so that it is possible to reduce a time required from start of the data reading to such a state that a passing current difference between the data lines reaches a level corresponding to storage data of the selected memory cell, and the data reading can be performed fast.
