Semiconductor memory device, memory system having the same, and method of operating the same
A semiconductor memory device, a memory system having the same, and a method of operating the same are provided. The semiconductor memory device includes a plurality of memory cells electrically coupled between a source select transistor and a drain select transistor, a peripheral circuit configured to perform a program operation on the plurality of memory cells, and a control logic unit configured to control the operation of the peripheral circuit so that at least two memory cells of the plurality of memory cells adjacent to the source select transistor and at least two memory cells of the plurality of memory cells adjacent to the drain select transistor are programmed to have a relatively fewer number of data bits than that of remaining memory cells of the plurality of memory cells in the program operation.
