Abstract: Various example embodiments provide a flash memory device, comprising a cell string; a page buffer connected to the cell string and a bit line and configured to sense data stored in a selected memory cell by precharging a sensing node connected to the bit line; and a voltage regulator. The page buffer comprises a latch including first and second inverters coupled between a latch node and an inverted latch node; and a pull-down NMOS transistor for tripping the sensing result of the selected memory cell to the latch node. The voltage regulator adjusts a trip voltage by providing the source voltage to the pull-down NMOS transistor. The flash memory device reduce a trip voltage variation range by using only the pull-down NMOS transistor characteristics. Also, an OFF cell margin and an ON cell margin may be secured by adjusting the level of the trip voltage using the source voltage.

Abstract: Disclosed is a charge pump of a flash memory, which includes a first stage pump that is connected between an output terminal and a first pump node, and a second stage pump that is connected between the first pump node and a second pump node. The first stage pump includes a first switch circuit that is connected between a power terminal and the first pump node and provides a power supply voltage to the first pump node in response to a first stage signal, in a normal operation, and a first pump circuit that generates a first pumping voltage by using a voltage of the first pump node in response to a first clock signal and provides the first pumping voltage to the output terminal. The first switch circuit blocks a current flow from the first pump node to the power terminal in a sudden power-off event.
