Abstract
PURPOSE: To secure the direct writing or reading and thus to facilitate the test by constituting the circuit with the scan-in path to supply the plural-bit test data to the feedback register in sequence and the scan-out path to deliver the test data in sequence.
CONSTITUTION: The circuit is constituted with the following units: logical operation part 13 and 14 which perform the logical operation for the data; feedback register 18 which supplies the output to the input of the logical operation part with the output of the operation part used as the input in order to form a feedback group; scan-in path 110 which supplies the test data of plural bits to register 18 in sequence; and scan-out path 111 which delivers the test data in sequence. With such constitution, the direct writing or reading can be facilitated with an easy testing ensured.
