He proposed coupling a tiny transistor with a capacitor, a miniature storage device that is either charged (1) or not (0). Capacitors leak over time, so Dennard envisioned repeatedly charging the capacitor via the transistor. The chip would be called a dynamic (due to the repeated charging) random access memory, or DRAM. These chips form the core of computer memory up to the present day. A DRAM chip worked like the old magnetic core memories, storing 1s and 0s with the help of electric currents. But rather than relying on wires and rings, DRAM circuits were carved into silicon. They didn’t
