Abstract
A semiconductor memory includes bit lines, word lines, memory cells coupled between the bit lines and the word lines, and a sensing circuit configured to sense a state of a selected memory cell. During a read operation of the selected memory cell, the electronic device is configured to precharge a selected word line to a first voltage, to precharge an unselected word line to a second voltage, to float the selected word line and the unselected word line, to apply a bit line voltage a selected bit line, to adjust a voltage level of the unselected word line using a first leakage current that flows between an unselected bit line and the unselected word line, to couple the selected word line and the unselected word line to the sensing circuit, and to compare a voltage level of the selected word line with the voltage level of the unselected word line.
