Abstract
A memory device includes a plurality of memory cells arranged in a plurality of planes and control circuitry configured to perform a multi-plane programming operation in which memory cells in each of the plurality of planes are programmed in a single programming operation. To perform the multi-plane programming operation, the control circuitry is configured to detect a neighbor plane disturb (NPD) defect during the multi-plane programming operation by performing a bit scan operation to identify, based on a first program verify threshold, a fast plane and a slow plane from among the plurality of planes, determining whether the fast plane passes a second program verify threshold greater than the first program verify threshold, identifying one of the fast plane and the slow plane as a failed plane based on the determination of whether the fast plane passes the second program verify threshold, and terminating programming of the identified failed plane.
