摘要： According to embodiments of the invention, a high-voltage generator circuit may include a voltage detector block that has a voltage divider, a discharge section, a comparator, and a control signal generator. The voltage divider generates a divided voltage at an output node by dividing a high voltage. The discharge section discharges the high voltage to a power voltage in response to a first control signal. The comparator determines whether the divided voltage reaches a reference voltage, and the control signal generator generates a second control signal in response to an output from the comparator and the first control signal. The voltage divider may include a high-voltage prevention circuit that prevents the high voltage from being applied to a low-voltage transistor of the comparator during a discharge period of the high voltage. The high-voltage prevention circuit may include a depletion-type or enhancement-type NMOS transistor having a high breakdown voltage.

摘要： A NAND flash memory device comprises a memory cell array comprising a plurality of memory cells, a plurality of page buffers, and an isolation circuit connected between the memory cell array and the plurality of page buffers. The isolation circuit comprises a high voltage transistor adapted to disconnect a first bit line connected to the memory cell array from a second bit line connected to the one of the page buffers during an erase operation of the NAND flash memory device. During the read operation, a third bit line arranged in parallel with the second bit line and connected to one of the page buffers is discharged to prevent the page buffer from being damaged due to coupling capacitance between the second and third bit lines.
