The electric charge on the capacitors slowly leaks off, so without intervention the data on the chip would soon be lost. To prevent this, DRAM requires an external [[memory refresh]] circuit which periodically rewrites the data in the capacitors, restoring them to their original charge. | The electric charge on the capacitors slowly leaks off, so without intervention the data on the chip would soon be lost.
