What is DRAM? How is it Different From SRAM?

Most likely, there’s a DRAM in the phone or computer you’re viewing this on. Dynamic random access memory is the most common type of RAM for personal devices -- learn how DRAM works and how it’s different than SRAM.

DRAM, or dynamic random access memory, is a type of RAM that stores each bit of data in a storage cell. As the word “dynamic” in the name might suggest, DRAM is in constant action -- a DRAM needs to be fed energy constantly to refresh every few milliseconds and keep data from being lost.

DRAM is commonly compared to another popular form of RAM -- static RAM. SRAM is used for cache memory devices -- like printers or routers -- while DRAM is used for networking, PCs, and gaming consoles.
