A new type of memory device is presented which takes advantage of the volume of a storage material in order to achieve extremely high information density and capacity. The unique properties of two-photon materials allows for reading and writing to any localized region throughout the volume of material. In addition to the high capacity the 2-photon 3-D memory system has been designed to access up to 106 bits in a single clock cycle. This large parallelism combined with an access time of 1/1 sec gives a memory bandwidth of 1012 bits/sec. It is shown that this value of memory bandwidth far exceeds that available from current memory systems and therefore is well-suited for the demands of current and future supercomputing systems. 1.
