dynamic RAM

dynamic RAM
   Abbreviated DRAM, pronounced "[dee-ram]." A common type of computer memory that uses capacitors and transistors storing electrical charges to represent memory states. These capacitors lose their electrical charge, so they need to be refreshed every millisecond, during which time they cannot be read by the processor. DRAM chips are small, simple, cheap, easy to make, and hold approximately four times as much information as a static RAM (SRAM) chip of similar complexity. However, they are slower than SRAM.
