Samsung announced plans to mass produce its CMM-D 3.1 memory modules in the fourth quarter of 2026. The modules are based on the CXL 3.1 standard and use a PCIe 6.0 interface.
Sampling begins Q3 2026
Each module can hold up to 1TB of memory and delivers a bandwidth of 72GB/s. Samsung claims performance is doubled compared to the previous CXL 2.0 generation, which offered a maximum of 256GB capacity and 36GB/s bandwidth.
Sampling of the CMM-D 3.1 modules is scheduled to begin in the third quarter of 2026. Mass production is expected to start in Q4 2026.
The new modules target data center and server applications that require expanded memory capacity. Samsung's announcement positions the CMM-D 3.1 as a significant upgrade over its predecessor.
