Abstract

Disclosed is an operating method of a controller for controlling an operation of a semiconductor memory device including a plurality of memory cells. In the operating method of the controller, program data to be stored in a selected page of the semiconductor memory device is generated, and the semiconductor memory device is controlled to program the program data in the selected page. Bit data at a predetermined position in the program data is data for allowing a threshold voltage of a corresponding memory cell to maintain an erase state.
