ABSTRACT:
A memory cell array includes a plurality of memory cells arranged in a matrix form. A word line and a power supply line respectively are connected in common to the plurality of memory cells arranged in each row. A power supply line/word line control circuit is connected to each word line and each power supply line. In accessing the plurality of memory cells row by row, the control circuit raises the voltage of the power supply line and, after the voltage of the power supply line reaches the high voltage at all the positions, starts activation of the word line. On the other hand, in turning from the access state to the non-access state, the control circuit deactivates the word line and, after the voltage of the word line changes to the ground voltage at all the positions, changes the voltage of the power supply line to the low voltage.
