Global Standards for the Microelectronics Industry
Main Memory: DDR4 & DDR5 SDRAM
Semiconductor memory plays an essential role in the development of countless electronic devices ranging from computers and gaming consoles to televisions and telecommunications products. JEDEC standards encompass virtually every key standard for semiconductor memory in the market today.
JEDEC published its widely-anticipated JESD79-5 DDR5 SDRAM standard in July 2020, and a second update, JESD79-5B, in August 2022. The standard addresses demand requirements being driven by intensive cloud and enterprise data center applications, providing developers with twice the performance and much improved power efficiency. JESD79-5B DDR5 is available for download from the JEDEC website. Read more about the DDR5 standard here.
