Dell confirms that CAMM memory won't remain proprietary
By Daniel Sims @RedSwirl - November 16, 2022

Recap: A laptop Dell introduced earlier this year may have brought about the first real alternative to the ancient DIMM and SO-DIMM standards. While there was some initial controversy, Dell has defended its new Compression Attached Memory Module (CAMM) standard due to its connectivity, speed, and efficiency advantages.

When Dell unveiled the Precision 7670 workstation laptop in April, some noticed that the company used it to introduce a new kind of RAM. RAM has used DIMM and SO-DIMM connectors for decades, and Dell might convince the industry to transition to CAMM.

Because Dell patented CAMM, worries spread that it would remain proprietary and that laptops using CAMM could only use RAM upgrades purchased from Dell. However, the company soon told PCWorld it intends to license CAMM out with help from the Joint Electron Device Engineering Council (JEDEC).

Dell may be the only company offering CAMM memory now, but it wants other vendors to support it in the future.

Compared to SO-DIMM, CAMM's connectors leave a shorter distance between the memory and the CPU.
One reason Dell is switching to CAMM is that it thinks SO-DIMM connections will soon reach their limit.

CAMM standard set to replace SO-DIMM for laptop memory
Could CAMM be a big buzzword in 2024?
By Shawn Knight - January 17, 2023

Something to look forward to: CAMM is one step closer to replacing the longstanding SO-DIMM memory module standard in laptops. JEDEC, the trade organization and standardization body that oversees memory standards for the computer industry, is in the process of adopting the CAMM Common Spec for laptops according to committee member Tom Schnell.

CAMM, which stands for Compression Attached Memory Module, was created by Schnell and introduced by Dell last year in its Precision 7670 workstation laptop. Schnell, who is also a Dell Senior Distinguished Engineer, told PCWorld that JEDEC has unanimously approved the 0.5 spec and is on target finalize the 1.0 spec by the second half of this year.

Schnell could not reveal which JEDEC member companies voted on the standard as that is up to each member to reveal, but the voting group covers a range of players with multiple interests.

SO-DIMM is not long for this world, and CAMM looks to be a way forward.
Dell and Schnell were quick to point out that CAMM is not a proprietary spec that would lock customers into a design.

"Dell is a huge company, we don't keep the lights on because we get royalties for a patent," Schnell said. "We basically want to recover the cost of inventing it, and implementing it."

Should everything go according to plan, CAMM-based systems could arrive as early as 2024.
