ABSTRACT:
In associative memory device, a search key is stored in the first storage element and a storage key is stored in the second storage elements, respectively via a first data bus. The search key is supplied to the comparator via a second data bus, and the storage key stored in the second storage element is supplied to the comparator. The comparator compares the search key with the storage key. When the storage key is consistent with the search key, the comparator delivers as the associative operation results a comparison consistency output signal to a priority encoder circuit which outputs code information having a limited bit length. This code information is transferred to CPU via a selector circuit. If the comparator delivers a comparison inconsistency output signal, this signal is directly passed to CPU via the priority encoder circuit, so that the contents of the first storage element is rewritten. The first and second storage elements are designated by an address signal and data is read or written via the first data bus, so that they are used as a usual memory device.
