The present invention aims to eliminate variations in threshold voltage subsequent to the writing of data in an EPROM. When a parasitic resistance between the source of a memory cell (M00) of an even-numbered row and its corresponding bit line (BL0) is larger by a resistance (R00) than a parasitic resistance between the source of a memory cell (M01) of an odd-numbered row and its corresponding bit line (BL0), a cell resistance compensating unit (40) having a compensating resistor (43) whose resistance value is equal to the resistance (R00) is provided between the bit line (BL0) and a ground potential (GND). When the memory cell (M00) is selected by a drain cell power-supply switching address (/AY0), a transistor (41) is turned on by the same signal (/AY0). When the memory cell (M01) is selected by a drain cell power-supply switching address (AY0), a transistor (42) is turned on by the same signal (AY0). The resistor (43) is inserted for the transistor (42), and resistance values from the sources of the memory cells (M00, M01) to the ground potential (GND) become equal to each other. Thus, variations in threshold voltage subsequent to the writing of data can be suppressed.

A system and method are disclosed for providing an electrically programmable read only memory (EPROM) in which each memory cell comprises an NMOS select transistor with a thick gate oxide and a PMOS breakdown transistor with a thin gate oxide. The source of the NMOS transistor and the source, drain and N well of the PMOS transistor are connected. The gate of the PMOS transistor is grounded.
