Abstract

A nonvolatile memory may include; a first memory cell array including a first selection transistor connected to a first string selection line, a second memory cell array including a second selection transistor connected to a second string selection line and spaced apart from the first string selection line by a first cutting line, and a peripheral circuit. The peripheral circuit may provide a first program voltage to the first selection transistor, provide a second program voltage to the second selection transistor different from the first program voltage, program the first selection transistor with a first threshold voltage in response to the first program voltage, and program the second selection transistor with a second threshold voltage level greater than the first threshold voltage in response to the second program voltage.
