In a semiconductor memory device and a method of operating the same, a memory block including memory cells is divided into memory groups. A level of bit line voltage applied to a bit line coupled to the memory cells included in each of the memory groups varies according to a distance between a row decoder and each memory groups during a program operation. Characteristics of the threshold voltage distribution of the memory cells in the semiconductor memory device may be improved without deteriorating performance of the program.
