Abstract
A page buffer of a nonvolatile memory device comprises a sense unit coupled between the sense node and the bit lines of a memory cell array, comprising a number of memory cells, and configured to precharge the bit lines to different voltage levels in response to a page buffer sense signal of a first or second voltage level, a MUX unit configured to output the page buffer sense signal of the first or second voltage level in response to a control signal according to a value of program data, a flag latch configured to temporarily store the program data and to output the control signal to the MUX unit, and a main latch configured to sense the voltage levels of the bit lines via the sense node and to perform a program verification operation.
