The invention provides a method for reinforcing memorizers by using a new low-redundancy two-dimensional matrix code, relates to a low-redundancy two-dimensional matrix code construction method and solves the problem of excessive redundancy bits when the two-dimensional matrix code is used for turning multiple units in the memorizers and carrying out error correction protection. One i-position information bit is arranged to be a m*n matrix, wherein m is a line number, and n is a column number. The low-redundancy two-dimensional matrix code constructed by the method is capable of correcting random one bit error and continuous two bit errors till maximum continuous n/2 bit errors; the number of the needed redundancy bits is (m-1)*n/2+n. The method is mainly applied to reinforcing protectionof the memorizers.
