Abstract
A memory device includes a plurality of planes. A method of programming the memory device includes applying a first program pulse to one or more memory cells of a first plane of the plurality of planes, verifying whether each one of the memory cells reaches a predetermined program state, and in response to a preset number of the memory cells in the first plane failing to reach the predetermined program state after the memory cells being verified for a predetermined number of times, bypassing the first plane when applying a second program pulse after the first program pulse.
Claims20
A method of programming a memory device, the memory device comprising a plurality of planes, the method comprising:
- applying a first program pulse to one or more memory cells of a first plane of the plurality of planes;
- verifying whether each one of the memory cells reaches a predetermined program state;
- and
- in response to a preset number of the memory cells in the first plane failing to reach the predetermined program state after the memory cells being verified for a predetermined number of times, bypassing the first plane when applying a second program pulse after the first program pulse.
A memory device, comprising:
- a plurality of planes each comprising a plurality of memory cells;
- a row driver coupled to the planes and configured to apply a first program pulse to one or more memory cells of a first plane of the plurality of planes;
- and
- a controller coupled to the row driver and configured to:
- verify whether each one of the memory cells reaches a predetermined program state;
- and
- in response to a preset number of the memory cells in the first plane failing to reach the predetermined program state after the memory cells being verified for a predetermined number of times, bypass the first plane when applying a second program pulse after the first program pulse.
