Abstract
A memory device includes a memory cell array having a plurality of memory blocks sharing a source line, a peripheral circuit for performing a program operation and an erase operation on a selected memory block among the plurality of memory blocks, and a control logic for controlling the peripheral circuit. The control logic controls the peripheral circuit such that some source select transistors adjacent to the source line among a plurality of source select transistors included in an unselected memory block among the plurality of memory blocks are floated in a source line precharge operation during the program operation.
