Abstract:
A system includes a memory device including a memory array including a plurality of wordline groups and control logic, operatively coupled with the memory array, to perform operation including causing a first erase verify to be performed sequentially with respect to each wordline group of the plurality of wordline groups, identifying a set of failing wordline groups determined to have failed the first erase verify, and causing a second erase verify to be performed sequentially with respect to each wordline group of the set of failing wordline groups.
