Abstract
A non-volatile semiconductor memory device, described herein, comprises a bit line, a source line, a memory string comprising a plurality of memory cells connected in series between the source line and the bit line, and control circuitry coupled to the plurality of memory cells, the source line, and the bit line. The control circuitry is configured to: determine if a program operation is a single-bit program operation or multi-bit program operation; in response to the determination, identify a voltage level to set the source line to during performance of the program operation; and perform the program operation on the memory string, the program operation including setting the source line to the voltage level.
