ABSTRACT:
A method for checking the refresh function of a memory having a refresh device includes the steps of, first, ascertaining whether or not refresh request pulses are being produced on the information memory and, if so, at what intervals of time from one another these refresh request pulses are produced. Next, a control unit for the information memory is supplied with refresh test pulses produced outside of the information memory instead of being supplied with the refresh request pulses. Then, the refresh test pulses are used to check a refresh device situated on the information memory.
