Designed to meet the memory-intensive workload demands of networking and data center applications, the DDR4 memory PHY delivers maximum performance and power efficiency while maintaining full compatibility with the DDR4 and DDR3 industry standards. With the Northwest Logic DDR4 Controller it comprises a complete DDR4 memory interface subsystem.
The Rambus DDR4 memory PHY delivers industry-leading data rates of up to 3200 Mbps and is compatible with the DDR4 and DDR3 standards. The PHY consists of a Command/Address (C/A) macro cell and Data (DQ) macro cells configured to create a 72-bit wide channel.
The Northwest Logic DDR4 controller maximizes memory bus efficiency via Look-Ahead command processing, bank management, auto-precharge and additive latency support. The core is DFI compatible and supports a range of interfaces to user logic.
The Rambus DDR4 PHY and Northwest Logic DDR4 controller used together comprise a complete DDR4 memory interface subsystem. Alternatively, these cores can be licensed separately to be paired with 3rd-party DDR4 controller or PHY solutions.
