An ultra fast data transfer speed is demonstrated for a novel three dimensional (3D) Static Random Access Memory (SRAM) consisting of multilayer silicon LSI chips on which GaAs LEDs and photodetectors are monolithically integrated for vertical optical interconnections. A unique feature of this system is the capability of parallel data transfer from one memory layer to the upper and lower memory layers by the optical interconnections. The results of static and dynamic simulations of the optically coupled 3D common memory have indicated that a block of 512 bits data can be transferred through four memory layers within 16 nsec. This is an equivalent data transfer speed of 128 Gbits/sec/layer.
