[Also in Division H1] A read-only memory capable of being programmed by radiant energy comprises a plurality of diode pairs such as 10, 11 connected baok-toback with a common junction arranged in an array of rows and columns, separate row and column conductors such as 41, 51 which are associated with each row and each column respectively of said diode array, the diodes being atranged with each of said diode pairs connected between a row conductor and a column conductor, and a corresponding plurality of semi-conductor photo-detectors such as at 16 arranged in an array of rows and columns, each of said photo-detectors being connected between the common junction of the corresponding diode pair and a point of bias potential, for example +2V. The photo-detectors are selectively illuminated through apertures in an opaque mask (Fig. 2, not shown). Each row conductor has a switch 42, 47 or 50 by which it is normally connected to a lockout line 43 (--V), whereby the diodes connected thereto (10, 20, 30, 12, 22 &c.) are biased into a low impedance state and the other diodes of the pairs into a high impedance state so that currents passing through illuminated photodetectors are conducted along the row conductors, i.e. away from the column conductors 51, 56 and 60. On the other hand, when it is desired to read-out a selected row, the corresponding switch 42, 47 or 50 connects the selected row conductor to a read line 44 (+ V) so that the diodes connected to that row are biased into a high impedance state in contrast to the other diodes of the pairs which are biased to a low impedance state, whereby currents from illuminated photo-detectors pass through diodes 11, 21, 31 &c. to the column conductors 51, 56 and 60 and to output amplifiers 52, 58 and 62. The photo-detectors are preferably photo-diodes or may comprise photo-transistors or photo-sensitive field effect transistors. The whole array may be constructed in the form of a semi-conductor monolothic structure using integrated circuit techniques (of Figs. 3-5, not shown). The diodes connected to the column conductors are shielded from the source of illumination.
