Abstract
An EPROM device may include a unit cell, a switching unit, a decoder, and a comparing unit. The unit cell may be disposed between a ground voltage terminal and a bit line coupled to a program voltage supply line. The switching unit may control an electrical coupling of the program voltage supply line and the unit cell according to input switching control signal. The decoder may generate a plurality of output signals according to an input of binary data. The comparing unit may compare each of a plurality of reference voltages with a bit lien voltage and generate a program mode output signal. The level shifter may receive at least one output signal of the output signals of the decoder and the program mode output signal, and may output the output signal of the decoder or the program mode output signal as the switching control signal.
