JEDEC and Argosy DDR5 SODIMM Status
DDR5 Market Info.
The CPU brands, Intel launched Alder Lake-S for Desktop in Nov. 2021, and followed by Alder Lake-H (for high performance laptop), Alder Lake-P and Alder Lake-U (both for mobile- ultra notebook) in Feb. 2022, which all supporting DDR5, PCI Express 5.0 and Thunderbolt 4 Type-C. AMD expect to introduce Ryzen 7000 for Desktop 3Q 2022, which will support DDR5, PCI Express 5.0 and Type-C up to USB 3.2 Gen 2x2 (20Gbps).
JEDEC & Argosy DDR5 SODIMM Sockets Status
JEDEC not yet published DDR5 262 Pin SODIMM Connector Standard, because the Signal Integrity standard of the 8.0mm and 9.2mm heights are to be determined. Still there were 24 reliability requirement fixed (mechanical, environmental & electrical). The Signal Integrity- skew, impedance and frequency domain were under discussion in 1Q 2022’s meeting, and the S-parameter is likely to adjust to higher criteria.Though JEDEC undisclosed vendors’ test result, Argosy conducted self-test and pass the higher criteria, based on the latest frequency adjustment.
(1) 3rd Parties Approved Best Performance
We joined DDR5 connector spec design with JEDEC & Intel since 2018, and launched DDR5 SODIMM sockets in 2019. Here are the summary of DDR5 SODIMM socket’s 3rd party tests.(2) Excellent Design & Manufacture Capability
We stepped in DDR market since 2006, to manufacture DDR2 & DDR3 sockets. As technology transition, we continued to develop DDR4 (SODIMM, DIMM SMT & DIP types) and now the DDR5 (SODIMM, RDIMM & UDIMM) sockets.(3) Well-organized Production Allocation
While COVID-19 outbreak, our factories faced shut down for a short period, but eventually were able to recover over 50% capacity within 3 weeks. Also, no material shortage since epidemic outbreak and even doubled production output in all products.
Summary
To sum up, DDR5 and DDR4 SODIMM differ in few aspects: DDR5 is 262 pins by adding 2 pins; connector housing become narrower and latch solder feet adjusted, to save PCB space; data speed increase 50% by 6.4Gbps; working voltage decrease 30% by 1.1V. All the improvement encourages gaming, commercial laptop and workstation to upgrade to DDR5 and highly rise DDR5 adoption to nearly 10% in two years.Argosy work with JEDEC on DDR5, and exploit our design and production technology to provide reliable quality and stable delivery, and has become customers’ strong supply partner.
