CAMM2: Revolutionizing Laptop Memory with JEDEC's Approval
The laptop RAM landscape is set for a significant transformation with the ratification of the CAMM2 standard by JEDEC. This new standard heralds the end of the over two-decade reign of the SO-DIMM form factor, ushering in a more compact and efficient era for laptop memory.

JEDEC's Ratification of CAMM2
JEDEC, the organization responsible for setting specifications for various memory types, has officially adopted CAMM2 as a standard. This move guarantees that CAMM2 will play a pivotal role in the design of future laptop generations.
Initially introduced by Dell in its Precision 7670 laptop as a proprietary technology, CAMM (now CAMM2) is set to replace the older SO-DIMM form factor. Dell's innovation aimed to create a thinner, more efficient form of laptop RAM, which has now been embraced as an industry standard.
Advantages of CAMM2 Over SO-DIMM
Slimmer Profile and Higher Performance
One of the most significant benefits of CAMM2 over the traditional SO-DIMM is its reduced thickness. Dell asserts that CAMM is 57% thinner than its predecessor. This slim profile not only saves space but also allows laptops to be designed more compactly. Additionally, CAMM2 is touted to surpass the 6,400MHz barrier of DDR5 SO-DIMM memory, offering potential for even higher clock speeds.
Overcoming the Limitations of Proprietary Technology
Addressing Upgradeability Concerns
Initially, CAMM's proprietary nature posed a challenge in terms of upgradeability, as Dell was the sole manufacturer. SO-DIMM, in contrast, benefited from widespread availability from numerous companies. The standardization of CAMM2 by JEDEC resolves this issue, paving the way for broader manufacturing and easier upgrades.
CAMM2 Specifications and Variants
DDR5 and LPDDR5(X) Support
The CAMM2 specifications include two distinct variants: one designed for DDR5 and another for LPDDR5(X). This development is particularly noteworthy as it introduces the possibility of non-soldered LPDDR5(X) memory, a significant step away from the current trend of soldered DDR5 RAM in laptops.
Pin-Out Differences Between Variants
It's important to note that the two CAMM2 variants have different pin-outs. This means that a motherboard designed for one type of RAM (DDR5 or LPDDR5(X)) cannot use the other variant. This distinction ensures that each variant is optimized for its specific memory type, although it does limit interchangeability.
In conclusion, the ratification of CAMM2 by JEDEC marks a new chapter in the evolution of laptop memory. By moving away from the older SO-DIMM form factor to a slimmer, more efficient CAMM2 standard, future laptops can be designed to be more compact while offering higher memory capacities and speeds. The standardization of CAMM2 also addresses previous concerns regarding upgradeability, making it a viable and promising option for the industry. As laptop designs continue to evolve, CAMM2's role in shaping these advancements will be closely watched and potentially widely adopted.
