Abstract
A semiconductor memory device, and a method of operating the same, includes a memory block including a plurality of pages, a read and write circuit configured to apply a first bit line voltage to a selected bit line corresponding to a selected memory cell and apply a second bit line voltage having a potential lower than that of the first bit line voltage to an unselected bit line during detrap operation, a voltage generation circuit configured to generate a first set voltage, a second set voltage, and a pass voltage during the detrap operation, and an address decoder configured to apply the first set voltage to a selected word line corresponding to the selected page and apply the second set voltage having a potential higher than that of the first set voltage to unselected word lines, during the detrap operation.
