QDR®-IV: The Next Generation of the Highest-Performance Memory Standard for Leading-Edge Networking Systems
As networking and computing equipment provider’s scale their solutions to meet the demands of the Internet, memory capabilities increasingly govern system performance gains. Routers, switches, and high-performance computing systems all require memories that can transact with processing elements at everincreasing rates. Random transaction rate (RTR), the number of random read or write accesses that a memory can support, therefore becomes the key memory metric. This white paper discusses how Cypress’s QDR®-IV provides the highest RTR and standards-based solution to meet these system challenges. It provides a detailed comparison of QDR-IV with alternate memory solutions like DRAM and RLDRAM. It also provides overview on the concept of Banking and its different implementations in QDR-IV, DRAM and RLDRAM.
