Abstract

Method of checking the functioning of the error- correction circuit in a computer comprising a memory and an error-correction circuit. By extending the functioning of the error-correction circuit to include handling one or more parity bits belonging to a word in the same way as the bits in said word are handled, and by carrying out a parity check on the unread word before the data bus is opened for transmission of the word, a test for the functioning of the error-correction circuit is obtained. <IMAGE>
