Goodbye, SO-DIMM: Memory overseer JEDEC will officially embrace the “CAMM Common Spec” as the next RAM module requirement for laptop computers.
JEDEC, the memory group that homologates RAM requirements, remains in the procedure of working out the brand-new specification to change the standard SO-DIMMs that have actually remained in usage for 25 years, according to JEDEC committee member, and Dell Senior Distinguished Engineer Tom Schnell.
Schnell really developed the initial CAMM— or Compression Attached Memory Module– style for Dell in 2015. JEDEC’s CAMM requirement will be based upon that CAMM style however is most likely to be rather various as business hammer it out.
While the adoption of brand-new hardware requirements can be filled, with hand-wringing, foot-dragging, and all the friction of a settlement amongst colleagues over where to get lunch, JEDEC appears to have actually handled it relatively quickly.
JEDEC’s CAMM will be based upon, however likely not precisely the like, Dell’s initial CAMM that was executed in some Dell Precision laptop computers in 2015.

In truth, Schnell stated, the approval reviewed rather well with the 20 business or two in the job group ballot for it.
” We have consentaneous approval of the 0.5 specification,” Schnell informed PCWorld. Schnell stated JEDEC is targeting the 2nd half of the 2023 to settle the 1.0 specification, with CAMM-based systems out by next year.
Who are the business that elected it? Schnell can’t state, as that’s up to each member to expose, however group covers the series of providers, from SoC, to ports, to OEMs, and all unanimously voted to embrace the CAMM Common Spec, without any dissenters. There are presently 332 business noted in JEDEC, from Apple to ZTE, each associated with various elements of memory in various markets.
For those who have not followed it, Dell presented its CAMM style in April 2022 with the goal of changing the years old SO-DIMM style that has actually been utilized in many video gaming and workstation laptop computers already. CAMM’s primary appeal is that it makes it possible for greater memory density while likewise scaling to ever greater clock speeds.
Some of the inspiration for usefulness most likely originates from the fast-approaching “brick wall” dealing with laptop computers when SO-DIMMs struck at DDR5/6400
Schnell stated the CAMM specification is far from settled, however the very first JEDEC CAMM modules need to take control of right where SO-DIMM ends at 6400.

CAMM is not exclusive
When Dell initially presented CAMM, it was rather misconstrued as an exclusive specification that would “lock consumers” into a style. Dell has stated that’s never ever been its objective and the quick approval appears to vindicate that. Schnell dealt with that preliminary issue, with the adoption underway.
” Dell is a substantial business, we do not keep the lights on due to the fact that we get royalties for a patent,” he stated. “We essentially wish to recuperate the expense of developing it, and executing it.”
Besides, going it alone is just not how the PC world works.
” We’re part of the PC market and the PC market is constructed out of an environment of partners, providers all feeding in,” Schnell stated. “Yes, Dell does excellent development of our own in our systems, however we likewise incorporate a great deal of developments from a great deal of individuals.”
The future of CAMM
With CAMM being worked out now, Schnell did set out some possible courses for CAMM as it changes SO-DIMM. DDR6 is an apparent roadway, he stated, however CAMM even makes it possible for the possibility of LPDDR6 on an exchangeable module. LPDDR, or low-power DDR RAM, has actually long been chosen for smaller sized and thinner laptop computers in addition to phones for power cost savings. It’s likewise long been carried out just as soldered-on
Schnell predicts a variation of CAMM allowing the efficiency and power advantages of LPDDR, however in a changeable and upgradeable module. With JEDEC embracing CAMM now, that future gets more detailed.
