| Feature | CPU Memory Controller | PCI Memory Controller | |---------|----------------------|------------------------| | Location | Inside CPU | On PCIe card/FPGA/device | | Access latency | Very low (~ns) | Higher (PCIe overhead) | | Capacity | Limited by CPU | Scalable via cards | | Coherency | Hardware-coherent | Usually not coherent (except CXL) | | Typical use | Main system RAM | Expansion, accelerators, memory pooling | This is the main system RAM – it’s

The on the NIC allows the network card to interact directly with the host system's memory. It acts as a "bridge" that translates network data packets into memory write commands that the host computer understands. CPU ──(PCIe bus)──&gt

This is the main system RAM – it’s separate memory controlled by a PCIe card.
