Double Data Rate 4 Synchronous Dynamic Random-Access Memory, authoritatively truncated as DDR4 SDRAM, is a kind of synchronous powerful random-get to memory with a high bandwidth ("twofold information rate") interface.

Released to the market in 2014, it is perhaps the most recent variation of dynamic random-get to memory (DRAM), of which some have been being used since the mid-1970s, and a higher-speed successor to the DDR2 and DDR3 advances.

DDR4 isn't good with any previous kind of random-get to memory (RAM) because of various flagging voltage and physical interface, other than different variables.

DDR4 SDRAM was discharged to the open market in Q2 2014, concentrating on ECC memory, while the non-ECC DDR4 modules opened up in Q3 2014, going with the dispatch of Haswell-E processors that require DDR4 memory.
