https://www.techpowerup.com/265238/ddr5-arrives-at-4800-mt-s-speeds-first-socs-this-year Cadence, a fabless semiconductor company focusing on the development of IP solutions and IC design and verification tools, today posted an update regarding their development efforts for the 5th generation of DDR memory which is giving us some insights into the development of a new standard. The new DDR5 standard is supposed to bring better speeds and lower voltages while being more power-efficient. In the Cadence's blog called Breakfast Bytes, one of Cadence's memory experts talked about developments of the new standards and how they are developing the IP for the upcoming SoC solutions. Even though JEDEC, a company developing memory standards, hasn't officially published DDR5 standard specifications, Cadence is working closely with them to ensure that they stay on track and be the first on the market to deliver IP for the new standard.
Marc Greenberg, a Cadence expert for memory solutions was sharing his thoughts in the blog about the DDR5 and how it is progressing. Firstly, he notes that DDR5 is going to feature 4800 MT/s speeds at first. The initial speeds will improve throughout the 12 months when the data transfer rate will increase in the same fashion we have seen with previous generation DDR standards. Mr. Greenberg also shared that the goals of DDR5 are to have larger memory dies while managing latency challenges, same speed DRAM core as DDR4 with a higher speed I/O. He also noted that the goal of the new standard is not the bandwidth, but rather capacity - there should be 24Gb of memory per die initially, while later it should go up to 32Gb. That will allow for 256 GB DIMMs, where each byte can be accessed under 100 ns, making for a very responsive system. Mr. Greenberg also added that this is the year of DDR5, as Cadence is receiving a lot of orders for their 7 nm IP which should go in production systems this year.
DDR5 will definitely be great in my opinion but motherboards and CPUs will be needed to support it. Next year will be the year for DDR5 and I fully expect AMD for example to change their CPU socket to accommodate it.
