Summary:Provided herein may be a semiconductor memory device and a method of operating the same. The semiconductor memory device may include peripheral circuits configured to perform a verify operation on selected memory cells by applying a verify voltage to a word line, and perform a compensation program operation on the selected memory cells by applying a compensation program voltage to the word line; and a control logic configured to control the peripheral circuits such that the compensation program operation is performed by applying the compensation program voltage to the selected memory cells to be programmed to a selected threshold voltage distribution among the threshold voltage distributions other than a highest threshold voltage distribution, wherein the compensation program voltage has a positive voltage lower than the main program voltage most recently applied to the word line.
