Modular LPDDR Memory Becomes A Reality: Samsung Introduces LPCAMM Memory Modules

Arthur T Knackerbracket has processed the following story:

Although Low Power DDR(LPDDR) memory has played a pivotal role in reducing PC laptop power usage, the drawback to the mobile-focused memory has always been its tight signaling and power delivery requirements. Designed to be placed close to its host CPU in order to minimize power expenditures and maximize clockspeeds, LPDDR memory is unsuitable for use in traditional DIMMs and SO-DIMMs - instead requiring that it be soldered down on a device in advance. But it looks like the days of soldered-down LPDDR memory are soon at an end, as this evening Samsung is announcing a new standard for removable and modular LPDDR memory: LPCAMM.

Pitched as an LPDDR-centric version of the upcoming Compression Attached Memory Module (CAMM) standard for removable mobile memory, LPCAMM is Samsung's take on using the same style of compression connector interface for LPDDR memory. The net result is that, thanks to the more exacting specifications and shorter trace lengths used by a CAMM-style connector, Samsung says it's possible to have modular and swappable LPDDR5 memory at last. And all in a fraction of the space a traditional SO-DIMM setup would occupy.

While the CAMM format has barely gotten off of the ground itself - JEDEC has yet to even approve the standard - Samsung is essentially opting to run with the idea to do something different with it by focusing on LPDDR memory. Notably, however, the resulting LPCAMM form factor is incompatible with CAMMs - both physically and electrically - so despite the similar names and use of compression connectors, the two are not interchangeable. But both pursue the same ideas for their respective memory types.
