Error correction circuit and error correction method

Abstract

An error correction circuit 1 in accordance with an aspect of the invention includes an associative memory 20, a logic circuit 10 disposed in parallel with the associative memory 20, and selection unit 30 that receives an output signal from the associative memory 20 and an output signal from the logic circuit 10 as an input. The associative memory 20 includes a table that handles an input signal as a word and holds an output signal related to the word and an error correction code used to correct the output signal as data. The associative memory 20 further includes error correction unit that outputs a signal in which an error was corrected based on data related to a word corresponding to an input signal. The selection unit 30 selects and outputs one of an output signal from the associative memory 20 and an output signal from the logic circuit 10.
