Abstract
The memory device includes a memory block with a plurality of memory cells that are arranged in a plurality of word lines. Circuitry is configured to program at least some of the plurality of memory cells in a program loop or that is configured to erase at least some of the plurality of memory cells in an erase loop. During the program loop or the erase loop, the circuitry is configured to perform a verify operation and an analog bitscan operation. In the analog bitscan operation, the circuitry counts the memory cells that pass or that fail the verify operation. The circuitry is also configured to determine an output of the analog bitscan operation, the output being one of at least three options.
