Abstract
A non-volatile memory device includes multiple word lines, and a voltage generator. Some of the word lines correspond to a deterioration area. The voltage generator is configured to generate a program voltage provided to multiple memory cells through the word lines. Control logic implemented by the non-volatile memory device is configured to control a program operation and an erase operation on the word lines. The deterioration area includes word lines of a first group and word lines of a second group. The control logic is configured to control a program sequence so that each of the word lines of the second group is programmed after an adjacent word line of the first group is programmed, and to control a distribution so that a threshold voltage level corresponding to an erase state of each of the word lines of the first group is higher than a threshold voltage level corresponding to an erase state of each of the word lines of the second group.
