WebApr 27, 2024 · 0. The critical point is that DRAM must be read to be refreshed correctly. You must read the capacitor voltage, then decide whether to refresh the value as a 0 or as a 1. But there is no 'continuous read circuit' built into high-density dynamic ram chips. You have to address the RAM cell to read it and refresh it.
