Abstract
An associative memory device in which a coincident output is held by each word and aging for word data can be efficiently performed such that the word data is made valid or invalid on the basis of the information. The associative memory device includes a plurality of words for storing data, for detecting the coincidence/non-coincidence between the data stored in the plurality of respective words and input search data. Each word further includes a memory for storing a coincidence line output by a searching operation, a storage memory for storing data representing whether the corresponding word is subjected to a searching operation or is available to write new data therein, a circuit for simultaneously setting/resetting the contents of the storage memory, and circuit for resetting/setting the memory for storing the coincidence line output by the storage memory.
