Several factors explain this dramatic improvement; the following section summarizes them and the rest of this document examines them in detail:
- Advances in CAM algorithms have reduced the number of DRAM reads required per search, resulting in more than a threefold increase in search rate.
- Enhancements in DRAM interface technology—including higher signaling speeds and more efficient bandwidth usage—have contributed to over a threefold boost in read rate per interface pin.
