On July 15, JEDEC solid state storage Association officially released ddr5 SDRAM memory standard specification, which opened the prelude of a new era of PC. According to the specification, the frequency (data transmission rate) of ddr5 memory starts at 3200mhz, which is the standard limit of DDR4, and the maximum can reach 6400mhz. According to the Convention, the actual product will greatly exceed this level, and the voltage will be further reduced from 1.2V to 1.1V. The capacity of a single die is 8-32gb (1-4gb). Today, SK Hynix, a South Korean storage giant, announced that it has officially released the world’s first ddr5 memory, and its frequency, capacity, energy efficiency and functional technology have reached a new height. < / P > < p > the ddr5 memory module launched by SK Hynix is a server oriented and data center oriented rdimm form. It is made of 16GB particles based on 1ynm process, with a single capacity of 64GB. With the help of TSV silicon perforation technology, the maximum ddr5 memory module can reach 256gb. < / P > < p > in terms of frequency, the starting point is 4800mhz, with a maximum of 5600mhz, which is equivalent to transmitting nine full HD movies in one second. < / P > < p > since it is rdimm memory module, ECC error correction can be automatically corrected even if it is 1 bit error, and the application reliability is claimed to be increased by 20 times. < / P > < p > according to the roadmap, sapphire rapids, the next generation server platform of Intel, will be the first to support ddr5 memory, as well as the PCIe 5.0 bus, CXL 1.1 heterogeneous interconnection protocol, etc., and will continue Intel’s built-in artificial intelligence acceleration strategy to support the latest “advanced matrix expansion” (amx) acceleration. It will be delivered in the second half of 2021. < / P > < p > as for the consumer platform, alder Lake 12 generation core is expected to support ddr5 at the end of next year or the first half of the following year, with the highest frequency of 4400mhz, the maximum system capacity of 128GB, and continue to support DDR4. According to the data from omdia, a market research agency, ddr5 memory market demand will begin to appear in 2021, with a global share of 10% in 2022 and 43% in 2024. Skip to content
