    Abstract: A memory device has a memory cell array with memory cells. A page buffer group generates page buffer signals according to a verify read result of the memory cells. A page buffer decoding unit generates a decoder output signal corresponding to the number of fail bits from the page buffer signals based on a first reference current. A slow bit counter outputs a count result corresponding to the number of fail bits from the decoder output signal based on a second reference current corresponding to M times the first reference current, where M is a positive integer. A pass/fail checking unit determines a program outcome with respect to the memory cells based on the count result and outputs a pass signal or a fail signal based on the determined program outcome.

    Abstract: Disclosed is a memory device which includes a memory cell array that includes a plurality of memory cells, and a peripheral circuit configured to perform a plurality of operations on the memory cell array by using a plurality of operating voltages. The peripheral circuit includes a voltage generating circuit including a first pump block, a second pump block, and a common pump block. The voltage generating circuit connects the first pump block and the common pump block in parallel to generate a first operating voltage among the plurality of operating voltages and connects the common pump block and the second pump block in series to generate a second operating voltage among the plurality of operating voltages. The common pump block is configurable to match the first pump block, the second pump block, or both, as needed.
