Abstract
A memory device includes a plurality of planes, a row driver and a controller. A method of programming the memory device includes in a program operation, the row driver applying a program pulse to a plurality of memory cells of a first plane of the plurality of planes; after the row driver applies the program pulse to the plurality of memory cells, the controller verifying if the plurality of memory cells have reached a predetermined program state; and if a preset number of the plurality of memory cells have failed to reach the predetermined program state after the plurality of memory cells have been verified for a predetermined number of times, the controller disabling the first plane.
Claims11
A method of programming a memory device, the memory device comprising a plurality of planes, a row driver and a controller, the method comprising:
- in a program operation, the row driver applying a program pulse to a plurality of memory cells of a first plane of the plurality of planes;
- after the row driver applies the program pulse to the plurality of memory cells, the controller verifying if the plurality of memory cells have reached a predetermined program state;
- and
- if a preset number of the plurality of memory cells have failed to reach the predetermined program state after the plurality of memory cells have been verified for a predetermined number of times, the controller disabling the entire first plane.
