Overview
The DDR4/3 PHY is compatible with JEDEC DDR3 and JEDEC DDR4 SDRAMs, supports a range of DDR3 DRAM speeds from 666Mbps to 2133Mbps and DDR4 DRAM speeds from 1866Mbps to 2400Mbps, and target support x16 DDR3/DDR4 SDRAM components, the design include an analog hard macro (CLK/CMD/ADDR/DQ/DQS) and a synthesizable digital design. It supports software auto training includes read gate, read/write data eye timing, and PHY Vref settings. Supports DDR4/DDR3 SDRAM.
Optimized for high performance, low latency, low area, low power, and ease of integration, the DDR4/3 PHY is provided as a hard DDR PHY that is primarily delivered as GDSII including integrated application-specific DDR4/3 I/Os. Supporting the GDSII-based PHY is the RTL-based PHY. The DDR4/3 PHY includes a DFI 4.0 interface to the memory controller and can be combined with controllers for a complete DDR (Double Data Rate) 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.
