Hi all

Recently Samsung announced memory-semantic CXL SSD.


I'm new in CXL and this is quite complicated...

This memory-semantic CXL SSD mapped to CXL.cache or CXL.? device ??

Yeahh, but firstly I'm trying to understand what the device is according to CXL sub-protocols...

Should be CXL.cache or CXL.mem if this CXL/SSD will operate like standard NVDIMM (DRAM + NAND).
