Optically coupled three-dimensional (3D) memory system is newly proposed for ultra fast parallel processing in computation. Several memory layers with LED's and photoconductors are stacked and the data transfer among these memory layers is performed by optical coupling in this memory system. Two kinds of new intelligent memories, an optically coupled 3D common memory (3D-OCCM) and an optically coupled 3D content addressable memory (3D-OCAM), are employed for simultaneously sharing data and implementing parallel data inspection.
