DRAM

Computer memory device in the form of a silicon chip commonly used to provide the immediate-access memory of microcomputers. DRAM loses its contents unless they are read and rewritten every 2 milliseconds or so. This process is called refreshing the memory. DRAM is slower but cheaper than SRAM, an alternative form of silicon-chip memory.
