DRAM

- an overview of Dynamic Random Access Memory, DRAM, a form of RAM, or Random Access memory widely used in computer and microprocessor applications.

Dynamic RAM is a form of random access memory, RAM. DRAM uses a capacitor to store each bit of data, and the level of charge on each capacitor determines whether that bit is a logical 1 or 0. However these capacitors do not hold their charge indefinitely, and therefore the data needs to be refreshed periodically. As a result of this dynamic refreshing it gains its name of being a dynamic RAM. DRAM is the form of semiconductor memory that is often used in equipment including personal computers and workstations where it forms the main RAM for the computer.
