Overview
This DDR (Double Data Rate) PHY IP supports DDR3/DDR3L/DDR4, provides low latency, and enables up to 1600Mbps throughput. The PHY IP is silicon proven and designed for ease of integration and faster time-to market.
The DDR PHY is interface between DDR controller and SDRAM. The DDR controller is used to control DRAM devices as well as to access the data stored on these devices. Provide multiple AXI interface for AXI master and support DFI standard for DDR PHY to support DDR4/3, data rate 1600Mbps, X8/X16, four ranks, Write leveling, Data training, low power mode and standby mode. The DDR PHY is used to control DRAM devices to access the data stored in these devices, provide SSTL135, POD12 and LVSTL interfaces for DDR3L, DDR4 and DDR3.
Optimized for high performance, low latency, low area, low power, and ease of integration, the DDR4, DDR3, DDR3L PHY is provided as a hard DDR PHY that is primarily delivered as GDSII including integrated application-specific DDR4, DDR3, DDR3L I/Os. Supporting the GDSII-based PHY is the RTL-based PHY. The DDR4, DDR3, DDR3L PHY includes a DFI 4.0 interface to the memory controller and can be combined controllers for a complete DDR interface solution.

DDR is most critical IP to SoC’s successful operation, because processors in SoC typically spends the majority of its cycles on reading and writing to DDR memory.
This whitepaper provides an overview of the JEDEC memory standards to help SoC designers select the right memory solution, including IP, that best fits their application requirements.
