Abstract

- A 4-kbit× 4-layer optically coupled three-dimensional (3D) common memory has been designed. The optically coupled 3D common (3D-OCC) memory is a newly proposed intelligent memory for a real-time parallel processor system in computation. This memory consists of a multilayered structure of two-dimensional (2D) memory with LED’s and photoconductors. Memory layers are optically coupled with each other through the LED’s 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 Gbits/s/layer is confirmed in the simulation.
