Holographic memories are an attractive candidate for future large capacity parallel associative search storage systems. Parallel retrieval of stored data is essential to many data processing applications, yet electronic implementations of associative memories are very costly. A straightforward extension of more conventional holographic storage techniques can be used to implement an associative memory. The various output beams for a two-dimensional page associative store are analyzed and separated to provide the desired output function. A correlation-type associative memory is also analyzed and compared with the first system. Applications of these memories are discussed for complex search algorithms and also for the potential of associative data processing.
全息存储器是未来大容量并行关联搜索存储系统的一个有吸引力的候选方案。存储数据的并行检索对于许多数据处理应用至关重要，然而关联存储器的电子实现成本非常高。一种更传统的全息存储技术的直接扩展可用于实现关联存储器。对二维页面关联存储的各种输出光束进行分析和分离，以提供所需的输出功能。还对一种相关型关联存储器进行了分析，并与第一个系统进行了比较。讨论了这些存储器在复杂搜索算法以及关联数据处理潜力方面的应用。
