Abstract
A string comparator is provided for searching the address of a stored string having substantially the same content as that of an input reference string. This comparator comprises a memory including a number of memory cells arranged in a matrix form having a plurality of rows and a plurality of columns. Each string is stored in the memory in such a manner that the row position of each of the memory cells corresponds to the content of a stored string and the column position of each of the memory cells corresponds to the address of the stored string. A row selector is coupled to the memory for selecting one row of the memory cell matrix corresponding to the content of the input reference string to be compared, so that the content of the memory cells belonging to the row selected by the row selector is read out.
