DRAM (Dynamic Random Access Memory)

By: admin Hardware

Dynamic RAM (DRAM), a dynamic and volatile nature, it is used to assist in computer processing speed and requires a refresh. In addition, DRAM is also used widely in computer memory unit for high density and low enough cost.

Prepared by the dynamic RAM cells - the cells that store data as a charge on the capacitor. Because capacitors have a natural tendency to empty the charge, then the dynamic RAM requires periodic charging of electric charge to maintain data storage.

Dynamic RAM stores one bit of data as payload information. Dynamic RAM using the gate capacitance of a MOS transistor substrate as an elementary memory cell. To keep the stored data remains intact dynamic RAM, the data must be refreshed by reading and rewriting data to memory. Dynamic RAM is used for applications that require a large RAM capacity, for example in a personal computer (PC).
