SOCAMM – Small Outline Compression Attached Memory Module. SOCAMMs provide over 2.5 times higher bandwidth at the same capacity when compared to RDIMMs, according to Micron. The SOCAMM form factor of 14x90mm occupies one-third of the size of the industry-standard RDIMM form factor. When using LPDDR5X memory, SOCAMM products consume one-third the power compared to standard DDR5 RDIMMs. SOCAMM implementations use four placements of 16-die stacks of LPDDR5X memory to enable a 128GB memory module.
We understand that SOCAMM is an AI server-specific memory and Nvidia is pushing for its standardization. Nvidia may use SOCAMM in its Grace Blackwell Ultra (GB300) GPU, which could increase demand markedly.
