Abstract
An associative memory capable of reducing erroneous searches is provided. A storage memory in the associative memory stores reference data. A comparator circuit receives externally applied search data and obtains the distance (for example, the Hamming distance) between the reference data and the search data. An oscillating circuit outputs a pulse signal with an oscillating frequency corresponding to the distance obtained by the comparator circuit. Similarly, the oscillating circuits output pulse signals with oscillating frequencies according to the distance between the reference data in corresponding storage circuits and the search data. A WTA circuit receives the pulse signals. Reference data stored in a storage circuit corresponding to an oscillating circuit that outputs a pulse signal with the highest frequency is determined as the most similar reference data (Winner) to the search data.
