In 1966, American engineer and inventor Robert Dennard invented dynamic RAM cells – single-transistor cells, each bit of information is stored in the form of an electric charge of a capacitor. By that time, MOS technology was already capable of creating capacitors. The presence or absence of a charge on a capacitor represents one or zero bits of information. And the transistor can control the recording of the charge into the capacitor. At the time, Dennard was working on a six-transistor me...| The CPU Shack Museum
