Parallel optical memories have been proposed to meet high speed, high capacity storage requirements for input/output intensive computer applications. This technology offers the capability for storage and retrieval of optical data in twodimensional pages resulting in high capacity and high throughput. Current raw bit error rates ofexperimental systems fall significantly short ofthe minimum industry requirement of 1012 for binary data. Thus, error control techniques for two-dimensional data are necessary in order for such memories to be commercially feasible. In this paper, we discuss severalerror control schemes suitable forpage-oriented data and specifically applicable to page-oriented optical memories. To better interface between the memory and the electronic host computer, we propose "smart" photodetector array devices in which the input is optical but the output is electronic. These arrays receive the optical signal from the memory and convert it to electronic data. Utilizing the speed of VLSI technology, the arrays perform fast paralleldecoding and data correction, thereby providing an efficient optoelectronic interface between the memory and the electronic computer.
