Paper Abstract

A new optical RAM-bus (ORAM-bus) memory has been proposed. This memory has three- dimensional memory structure with the vertical optical interconnection. Data are vertically transferred in this memory by the optical coupling sense amplifier which acts as a cache memory and also as an amplifier to amplify the signal read-out from a memory cell. It was confirmed in the computer simulation that a very high data transfer speed of 64 Gbit/s can be achieved in the ORAM-bus memory with the configuration of 256 Kbits X 4 layers. The new parallel computer system with such ORAM-bus memories is also proposed.
