Abstract :
The optically coupled three-dimensional common (3D-OCC) memory is an intelligent memory for a real-time parallel processor system. It consists of a multilayered structure of two-dimensional memory with LEDs and photoconductors. The memory layers are optically coupled with each other through the LEDs and the photoconductors. Data are transferred in the vertical direction by optical coupling, while the conventional memory operations are performed in the horizontal planes. Very fast optical data transfer of 32 Gb/s/layer is confirmed in the simulation
