ABSTRACT:
An apparatus for retrieving or searching character strings which can be fabricated with a simplified structure and operate at a high speed. A memory circuit storing a standard character string is employed. The memory circuit includes a plurality of input lines each corresponding to one of the characters in the standard character string, a plurality of output lines and memory cells. Each of output lines of the memory circuit is used to enable transfer operation of one stage of a sequential logic circuit, and a detection output is derived from the sequential logic circuit when all the stages are enabled in a predetermined order.
