Fixed, associative memory using evaporated organic diode arrays

The use of fixed or read-only memories to store permanent or semi-permanent data has been widely treated in the literature. Associative or content-addressable memories, discussed more recently, provide the important capability for rapid parallel searching and retrieval of stored information. A fixed, associative memory can be used in applications requiring storage of encyclopedic data which must be searched at very high speed. Large capacity stores such as library and other catalog search files, language translators and medical diagnostic tables, as well as small stores such as code converters, computer program memories and other realtime search files, may be of this type.
