HOLOGRAPHIC ASSOCIATIVE MEMORY WITH ACCURATE ADDRESSING

We demonstrate the weakness of the real-time holographic associative m emory implementation in addressing accuracy and describe a novel metho d to implement associative memory with accurate addressing. In this me thod, the memory images and their background images are stored in two common holographic memory systems, and the partial image and its backg round image are simultaneously used to address the two holographic mem ory systems. The experimental results have proved the system feasible. In addition, we describe a method of associative memory with accurate addressing in a common real-time holographic memory system using comb inatorial memory images and combinatorial addressing images.
