ABSTRACT:
A ratioless semiconductor read only memory circuit comprises a plurality of insulated gate field-effect transistors being arranged in the form of a matrix consisting of columns and columns, bit lines of the rows of the transistors connected in parallel a sampling transistor connected in series to each of the rows of the transistors and each of the bit lines, and a row selection circuit connected to the respective bit lines for selecting one of the bit lines. The transistors of said array corresponding to individual bits are of the enhancement type or the depletion type depending on desired logic content.
