ABSTRACT:
A read only memory cell for storing a multiple bit value is disclosed. The read only memory cell comprises: at least three output lines, each of the at least three output lines representing a different multiple bit value; a switching device connected between a single one of the three output lines and a voltage source. The switching device provides an electrical connection between the voltage source and the single one of the three output lines in response to a switching signal, a voltage of the connected output line switching value in response to connection to the predetermined voltage and the multiple bit value represented by the output line is thereby selected. There is also an output device provided for outputting the selected multiple bit value.
