<p>PROBLEM TO BE SOLVED: To prevent DRAMs mounted on a memory board or memory module from going to a refresh mode all at once, resulting in the temporary flow of a high current causing overlapped power noises. SOLUTION: The storage has a decode chip 20 comprising a circuit 22 for judging a refresh mode, based on input control signals RE, CE and signal switching circuit 24 for generating control signals shifted in time to be fed to dynamic RAMs 11A-11D when the circuit 22 judges the mode to shift the dynamic RAMs 11A-11D to a self refreshing operation.</p> |
