Abstract
The present disclosure relates to a memory device and a memory system including the same. The memory device includes a memory cell storing data, a voltage generation circuit selectively outputting a program voltage and verify voltages in response to an operation control signal, a page buffer including first latches and second latches, and storing first data sensed by a first sensing current in the first latches and second data sensed by a sensing current greater than the first sensing current in the second latches during a verify operation using the verify voltages, and a pass/fail check circuit determining a pass or fail of the verify operation of the memory cell according to the first data and allowable bits.
