ABSTRACT:
A diode type read only memory (ROM) includes a diode as a memory cell. The diode is a logic level "on" memory cell and coupled to one of the word lines and one of the bit lines of the ROM. A relative high voltage is given to the bit line coupled to the diode and a relative high voltage is given to the corresponding word line. Therefore, the data saved in the diode can be read out.
