Abstract
A memory device includes a memory block, a peripheral circuit, and control logic. The memory block includes memory cells. The peripheral circuit performs a program operation including a plurality of program loops. Each of the plurality of program loops includes a program pulse application operation and a verify operation. The control logic controls the peripheral circuit to store cell status information and apply a program limit voltage. The control logic sets a verify pass reference and applies the program limit voltage determined based on the cell status information.
