Abstract
A memory device includes a semiconductor substrate in which memory circuitry has been fabricated. An address converter and a control signal converter are coupled to an address decoder and control logic, respectively. The address and control converters are operable to receive and convert optical address and control signals, respectively, into corresponding electrical address signals applied to the address decoder and control signals applied to the control logic. A read/write circuit on the substrate is coupled to a data converter formed in the substrate. The data converter is operable to receive and convert optical write data signals into corresponding electrical data signals to be applied to the read/write circuit and to receive and convert electrical read data signals into corresponding optical read data signals.
