Abstract
A SIMM (single in-line memory module) board is provided with a plurality of integrated semiconductor memory or other integrated semiconductor circuit devices which include, as a part of each integrated circuit device, a current spike leveling capacitor. The capacitor is on the die side of circuitry connecting the device to the board. By connecting the on-chip capacitors of the integrated circuit devices in parallel, sufficient capacitance is provided to stabilize current to all of the integrated circuit devices.
