Abstract
A memory device according to an embodiment includes a plurality of cell strings each including a select transistor and memory cells connected in series, a peripheral circuit configured to apply a verify voltage to the select transistor and perform an internal operation on the memory cells, and control logic configured to control the peripheral circuit to apply an operation voltage for the internal operation. The control logic includes a bad string management component configured to verify threshold voltages of the select transistor and control the peripheral circuit to perform the internal operation on a cell string including a select transistor passed in verification according to a verify result of the select transistor.
