ABSTRACT:
A process for controlling an optical pnpn thyristor to be driven comprises a step of applying a train of pulses to maintain a low impedance state of an optical pnpn thyristor which is shifted beforehand to be in the low impedance state by a positive set pulse. Each of the train of pulses is less than in its level than the positive set pulse. When light emission is required for the reading of an information, a positive set pulse is applied to the optical pnpn thyristor. As a result, electric power consumption is reduced during a time storing the information.
