ABSTRACT:
A method and apparatus for testing the self-refresh operation of a dynamic memory part are provided in which an oscillator (140) is coupled to a self-refresh counter (142). The self-refresh counter (142) causes a refresh row address counter (144) to generate row addresses for self-refresh cycles. The refresh row address counter (144) is coupled to a self-refresh control circuit (148). The self-refresh control circuit (148) is operable to generate a signal indicating completion of a self-refresh cycle. The refresh row address counter (144) is also coupled to a multiplexer (146). The multiplexer (146) outputs row addresses from either the refresh row address counter (144) or those supplied externally for rows to be refreshed.
