Abstract
Provided are a semiconductor memory device and an operating method thereof. The semiconductor memory device includes a memory cell array including a plurality of strings, wherein each of the plurality of strings includes a first memory cell group, and a second memory cell group and peripheral circuits configured to generate a first precharge voltage applied to the first memory cell group and a second precharge voltage applied to the second memory cell group when a channel precharge operation is performed during a program operation, and generate a program voltage to apply the program voltage to the memory cell array when a program voltage application is performed.
