Abstract
A memory device performs a coarse-program operation and a fine-program operation. During the coarse-program operation, the memory device selectively precharges a bit line to perform a verification. During the fine-program operation, the memory device precharges all bit lines to perform the verification.
Claims20
A memory device comprising:
- a bit line coupled to a memory cell;
- a precharge control circuit configured to generate a bit line precharge signal based on a program operation information signal;
- and
- a page buffer configured to generate a latch signal based on program data and a voltage level of a sensing node, which is coupled to the bit line, and configured to precharge the bit line responsive to at least one of the bit line precharge signal and the latch signal.

A memory device comprising:
- a bit line coupled to a memory cell;
- a precharge control circuit configured to generate a bit line precharge signal responsive to at least one of:
- a program operation information signal and a verification information signal;
- and
- a page buffer configured to generate a latch signal by sensing program data and a voltage level of a sensing node, which is coupled to the bit line, and configured to precharge the bit line responsive to at least one of:
- the bit line precharge signal and the latch signal.
3 more elements
A method of operating a memory device comprising a plurality of bit lines, the operating method comprising:
- applying a program voltage to a plurality of memory cells;
- and
- selectively precharging a plurality of bit lines to perform a verification when the program operation is a coarse-program operation, and precharging all the plurality of bit lines to perform the verification when the program operation is a fine-program operation.
