DRAM uses a single transistor and capacitor per memory bit to store digital data

IBM researcher Robert Dennard patented Dynamic Random-Access Memory in 1966. By storing each binary bit of data as an electric charge in a single capacitor controlled by one transistor, DRAM permitted far higher memory density than multi-transistor static RAM. Because charge leaks over time, DRAM requires periodic electronic refresh cycles.
