Abstract:
A method of operating a semiconductor memory device includes applying a program pulse at least once to each of a plurality of pages; performing a pre-read operation on a reference page among the plurality of pages through an initial test voltage; repeating the pre-read operation by controlling the initial test voltage until a result of the pre-read operation is a pass; setting the initial test voltage of when the result of the pre-read operation is the pass as a reference test voltage; and detecting a defective page among the plurality of pages by performing read operations on the plurality of pages through the reference test voltage.

Claim (Index 23):
A semiconductor memory device, comprising:\n a memory cell array including a plurality of memory blocks, each of which includes a plurality of pages coupled to each of the plurality of word lines; and a peripheral circuit suitable for performing a program operation on each of the plurality of pages, wherein during the program operation, the peripheral circuit performs a program operation on a selected page, verifies whether or not a result of the program operation is a pass by applying a verify voltage to a word line of the selected page, and repeats the program and verifying until the result of the program operation is the pass, and wherein the peripheral circuit further increases threshold voltages of memory cells included in the plurality of pages by applying an additional program pulse at least once to the plurality of word lines, and detects a defective page among the plurality of pages by performing read operations on the plurality of pages through a reference test voltage greater than the verify voltage by an amount of a determined voltage.
