First Dynamic Random Access Memory
Dynamic Random Access Memory (DRAM) is a type of internal computer memory created by Dr. Robert Dennard at IBM in 1966. DRAM is included in some of the first moves away from magnetic data storage. There were earlier and faster types of RAM, but due to costs, DRAM is the most modern and common type, consisting of one transistor and one capacitor, but can contain billions of memory cells. While the capacity for data is high, DRAM slowly loses data over time and must often be reinscribed and continuously connected to a power source.
