ABSTRACT:
In order to achieve defined potentials on unselected column lines, in a read only memory module in which storage elements are arranged between intersecting row lines and column lines, each column line is connected to a fixed auxiliary voltage by way of an auxiliary resistor and the value of the auxiliary voltage is more negative than the voltage on the row line selected during a read operation and the value of the auxiliary resistors is sufficiently large that the current on a selected column line flowing from the auxiliary voltage source by way of the auxiliary resistor into the selected column line is small vis-a-vis the read current flowing in the column line.
