Short for Dynamic Random Access Memory, DRAM is one of the most commonly found RAM modules in PC compatible personal computers and workstations. It stores its information in a cell containing a capacitor and transistor; because of this design, these cells must be refreshed with new electricity every few milliseconds for the memory to keep holding its data. DRAM was first invented and patented by Robert Dennard in 1968 and first released commercially by Intel in October 1970. The image below shows a memory module with eight DRAM integrated circuits on its visible side.

Note: This type of memory is a volatile memory, meaning that if it is disconnected from power, the information within the memory is lost.
