Abstract
An operating method of a semiconductor device includes applying a read voltage to a selected word line of a selected memory block, among a plurality of memory blocks including cell strings coupled between bit lines and a source line, detecting a voltage of the source line by forming a channel in cell strings of the selected memory block, comparing the voltage of the source line with a reference voltage corresponding to the selected memory block, and performing a least significant bit (LSB) read operation on memory cells coupled to the selected word line when the voltage of the source line is greater than the reference voltage, as a result of the comparing, and performing a most significant bit (MSB) read operation on the memory cells when the voltage of the source line is less than the reference voltage, as the result of the comparing.
