The Korean company Hynix presented to the public the first of its kind DDR5 RAM, about which in the official blog of the company.
According to SK hynix, the new memory provides data transfer rates of 4,8-5,6 Gbps per pin. This is 1,8 times more than the baseline memory of the previous generation DDR4. At the same time, the manufacturer claims that the voltage on the bar is reduced from 1,2 to 1,1 V, which, in turn, increases the energy efficiency of DDR5 modules. Support for error correction ECC - Error Correcting Code was also implemented. This feature is said to improve application reliability by up to 20 times over previous generation memory. The minimum amount of board memory is declared at the level of 16 GB, the maximum - 256 GB.
The new memory was designed according to the specification of the standard , which was published on July 14, 2020. According to the then JEDEC announcement, the DDR5 specification supports twice the real channel as DDR4, that is, up to 6,4 Gb / s for DDR5 against the available 3,2 Gb / s for DDR4. At the same time, the launch of the standard will be βsmoothβ, that is, the first bars, as the association planned and as SK hynix shows, are only 50% faster in the database compared to DDR4, that is, they have a channel of 4,8 Gb / s
According to the announcement, the company is ready to switch to the mass production of memory modules of the new standard. All preparatory stages and tests, including testing by manufacturers of central processors, have been passed, and the company will start actively releasing and selling a new type of memory as soon as equipment corresponding to the specifications appears for it. Intel actively participated in the development of the new memory.
Intel's involvement is no accident. Hynix says that while the main consumer of new generation memory, in their opinion, will be data centers and the server segment as a whole. Intel Corporation still dominates this market, and in 2018 - it was then that the active stage of collaboration and testing of new memory began - it was the undisputed leader in the processor segment.
Jonghoon Oh, Executive Vice President and CMO of Sk hynix stated:
SK hynix will focus on the fast-growing premium server market, strengthening its position as the leading server DRAM company.
The main stage of entering the market of new memory is scheduled for 2021 - it is then that the demand for DDR5 will begin to grow and at the same time equipment capable of working with the new memory will βsuitableβ for sale. Synopsys, Renesas, Montage Technology and Rambus are currently working with SK hynix to build the ecosystem for DDR5.
By 2022, SK hynix predicts that DDR5 memory will capture a share of 10%, and by 2024 - already 43% of the RAM market. True, it is not specified whether server memory is meant, or the entire market, including desktops, laptops and other devices.
The company is confident that its development, and the DDR5 standard in general, will be extremely popular among specialists working with big data and machine learning, among high-speed cloud services and other consumers for whom the speed of data transfer within the server itself is important.
