: CXL-based memory expansion offers approximately 8x lower latency compared to network-based RDMA (Remote Direct Memory Access).

: A 2MB buffer on each device receives "CENT instructions" from a host CPU. These are then decoded into micro-ops for the memory units. pim073.jpg

PIM is a computing paradigm where data processing occurs directly within the memory chips (like DRAM) rather than moving it back and forth to a central CPU or GPU. This eliminates the "memory wall"—the performance bottleneck caused by the slow and energy-intensive transfer of data between memory and processors. 2. The CENT Architecture : CXL-based memory expansion offers approximately 8x lower
