Abstract
A semiconductor memory apparatus includes an access line control circuit. The access line control circuit applies a selected bias voltage to a selected access line coupled with a target memory cell and applies a first unselected bias voltage to an unselected access line adjacent to the selected access line. A second unselected bias voltage is applied to an unselected access line not adjacent to the selected access line.
