DYNAMICRANDOMACCESSMEMORY

Dynamic random-access memory

Dynamic random-access memory is a type of random-access memory that stores each bit of data in a separate capacitor within an integrated circuit. The capacitor can be either charged or discharged; these two states are taken to represent the two values of a bit, conventionally called 0 and 1. Since capacitors leak charge, the information eventually fades unless the capacitor charge is refreshed periodically. Because of this refresh requirement, it is a dynamic memory as opposed to SRAM and other static memory.

Noun

  1. Dynamic RAM is typically the RAM used as the main memory in a computer system. DRAM requires fewer transistors per bit than SRAM, but each bit needs to be refreshed regularly or it will lose information. DRAM is typically slower but much less expensive than SRAM.
