Abstract:
A semiconductor memory device and a method of operating the same are provided. The method of operating the semiconductor memory device includes determining a target word line coupled to an over-programmed memory cell, backing up data stored in memory cells coupled to the target word line in a second memory area, wherein the se second memory area is different from a first memory area where the memory cells coupled to the target word line are disposed, and applying a stepped-up read pass voltage to the target word line when a read operation is performed on a selected memory cell in a memory block coupled to the target word line, wherein the selected memory cell is different from the over-programmed memory cell. Therefore, the operation reliability of the semiconductor memory device is improved.

Claim (Index 15):
A semiconductor memory device, comprising:\n a memory cell array including a plurality of memory cells; a peripheral circuit configured to perform a data program operation, a data read operation, and a data erase operation on the memory cell array; and a control logic configured to control the peripheral circuit such that the data program operation, the data read operation, and the data erase operation on the memory cell array are performed, wherein when an over-programmed memory cell is present in the memory cell array, the control logic is configured to:\n back up data stored in a target page, which corresponds to a target word line to which the over-programmed memory cell is coupled, in a second memory area in the memory cell array, the second memory area being different from a first memory area where memory cells corresponding to the target page are disposed, and \n control the peripheral circuit such that a stepped-up read pass voltage is applied to the target word line when a read operation is performed on a selected memory cell in a memory block coupled to the target word line, the selected memory cell being different from the over-programmed memory cell.
