JEDEC and Argosy DDR5 SODIMM Status

DDR5 Market Info.

Many market researchers forecasted the DDR5 shipment will increase to over 20% in 2022. Though the DDR5 began shipment in 2021, but the delay of new CPU makes DDR5 adoption slower. It’s expected DDR5 to achieve around 10% market adoption by end of 2022, and increase to 20% by 2023 and excess DDR4 by 2024.

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).


In summary, the generation of DDR5, PCIe 5.0 and Thunderbolt 4 has come. Argosy’s DDR5, USB4 & Thunderbolt 4 connectors are all entered mass production, and deliver near 400K pcs DDR5 and 4,300K pcs Thunderbolt 4 Type-C. Our PCIe 5.0 will also be ready by 2022.


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.


In fact, we began to deliver DDR5 SODIMM connector (4.0 height) in 1Q 2021, and the yearly shipment is 290K pcs. There are three reasons why customers are confident of our DDR5 SODIMM sockets.

(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.

Ÿ   DDR5 4.0 height pass the Signal Integrity performance, 3 in 5 vendors pass, tested by JEDEC (Oct. 2020)

Ÿ   DDR5 8.0 height is the ONLY pass Signal Integrity performance among 3 vendors, tested by JEDEC (Oct. 2020)

Ÿ   Spec-in over 15 customers, including gaming laptop, commercial laptop, workstation, Chromebook brands and Intel POC*

DDR5 5.2 height apply to the same SI criteria as 4.0 height; 9.2 height apply to the same SI criteria as 8.0 height

*POC refers to Proof of Concept

(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.


Our DDR3/4 SODIMM has gradually increase market share, from 30% in 2016 to over 50% in 2021. In 2021, our DDR3/4 SODIMM shipment achieved nearly 130KK pcs. Today, our DDR SODIMM series production capacity achieves 12KK pcs per month. With the increasing awareness of production re-allocation, we keep expanding production in Taiwan & China, and plan to setup new site in ASEAN.

(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.


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.
