Abstract
The present application provides a memory device, a method for operating a memory device, and a memory system. The memory device includes a memory array and a peripheral circuit coupled to the memory array, the memory array includes a memory block, and the memory block is coupled to the peripheral circuit through a word line. The memory block includes programmed memory cells and an unprogrammed memory cell, and the programmed memory cells include a first and a second memory cell. The peripheral circuit is configured to: perform a program operation on a third memory cell in the memory block, apply a first voltage to a first word line coupled to the first memory cell in a first phase of a channel preparation phase of the program operation; and apply a second voltage to a second word line coupled to the second memory cell.
