Today, virtually all SDRAM is manufactured in compliance with standards established by [[JEDEC]], an electronics industry association that adopts [[open standards]] to facilitate interoperability of electronic components. JEDEC formally adopted its first SDRAM standard in 1993 and subsequently adopted other SDRAM standards, including those for [[DDR SDRAM|DDR]], [[DDR2 SDRAM|DDR2]] and [[DDR3 SDRAM]].

[[Double data rate]] SDRAM, known as [[DDR SDRAM]], was first demonstrated by Samsung in 1997.<ref name="techpowerup">{{cite web |title=Samsung 30 nm Green PC3-12800 Low Profile 1.35 V DDR3 Review |url=https://www.techpowerup.com/review/samsung-mv-3v4g3/ |website=TechPowerUp |access-date=25 June 2019 |date= March 8, 2012}}</ref> Samsung released the first commercial DDR [https://medium.com/@dimasatmed/pengertian-fungsi-jenis-jenis-random-access-memory-ram-8b5824c0bcf2 SDRAM] chip (64{{nbsp}}Mbit{{binpre}}) in June 1998,<ref name="samsung99"/><ref name="samsung98"/><ref name="phys"/> followed soon after by [[Hyundai Electronics]] (now [[SK Hynix]]) the same year.<ref name="hynix90s">{{cite web |title=History: 1990s |url=http://www.az5miao.com/history1990.html |website=az5miao |access-date=4 April 2022}}</ref>

SDRAM is also available in [[Registered memory|registered]] varieties, for systems that require greater scalability such as [[Server (computing)|server]]s and [[workstations]].
