Abstract
A memory device includes pages each constituted by memory cells, and a page write operation and a page erase operation are performed. First and second impurity layers and first and second gate conductor layers in each memory cell is connected to a source line, a bit line, a word line, and a driving control line. In a page read operation, page data is read. In the page write and read operations, a selected driving control line is lowered to zero volt at a first reset time, the driving control line is isolated from a driving circuit at a second reset time, thereby putting the driving control line in a zero-volt floating state, and a selected word line is set at zero volt at a third reset time, thereby putting the driving control line in a negative-voltage floating state by capacitive coupling between the word line and the driving control line.
