Memory device performing program operation and method of operating the same

Abstract

The present technology relates to a semiconductor device. According to the present technology, a memory device having a reduced size may include a plurality of memory cells connected to a selected word line, a plurality of page buffers configured to store at least one second logical page data except for first logical page data in a plurality of first program loops performed on the plurality of memory cells, and store the first logical page data after the plurality of first program loops are performed, and a control logic configured to control the plurality of first program loops based on the at least one second logical page data, determine first memory cells programmed to one program state based on the first logical page data, and control a plurality of second program loops performed on second memory cells.
