Design specification: For each equivalent 1 MB of electric RAM [8 million electric transistors], figure about 256 thousand optical transistors, since each "bit" can hold 1 value [assuming 4-byte integer or whatever tech allows]. And find a new name for "bit" will ya? Whatever it is, you can build them bigger and cheaper for the same performance.
