JEDEC Plans LPDDR6-Based CAMM, DDR5 MRDIMM Specifications
by Anton Shilov on July 23, 2024 7:00 PM EST Following a relative lull in the desktop memory industry in the previous decade, the past few years have seen a flurry of new memory standards and form factors enter development. Joining the traditional DIMM/SO-DIMM form factors, we've seen the introduction of space-efficient DDR5 CAMM2s, their LPDDR5-based counterpart the LPCAMM2, and the high-clockspeed optimized CUDIMM.
Additionally, a "Tall MRDIMM" form factor is in the works (and pictured above), which is designed to allow for higher capacity DIMMs by providing more area for laying down memory chips. New memory technologies typically require new DIMMs to begin with, so it's important to clarify that this is not unexpected, but at the end of the day it means that the LPCAMM will be undergoing a bigger generational change than what we usually see. But with MRDIMMs already shipping for Intel systems – and similar AMD server parts due a bit later this year – the formal version of that standard should be right around the corner.
