 DRAM @ Wikipedia
Dynamic random access memory (DRAM) is a type of random access memory that stores each bit of data in a separate capacitor within an integrated circuit.
Since real 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.
Its advantage over SRAM is its structural simplicity: only one...
