Abstract
A semiconductor memory device and a method of operating the same are provided herein. The semiconductor memory device includes first and second pages, a peripheral circuit, and a control logic. The first page includes first memory cells, each storing N bits. The second page includes second memory cells, each storing N−1 bit. The peripheral circuit performs a first program operation that results in a threshold voltage of each first memory cell to be included in one of 2states and performs a second program operation that results in a threshold voltage of each second memory cell to be included in one of 2states. The control logic controls the first and second program operations through the peripheral circuit and controls the peripheral circuit to perform the second program operation by using at least one, but not all of a plurality of verify voltages that are used in the first program operation.
