DDR4 Controller
Design IP
Overview

DDR (Double Data Rate) is a computer memory technology utilized in RAM (Random-Access Memory) modules, enabling data to be transferred twice during each clock cycle, which significantly elevates memory speed, efficiency and robust error-handling capabilities. DDR4 memory is widely deployed in various devices, including laptops, desktop computers, servers, gaming consoles, and high-performance workstations. It plays a pivotal role in enhancing data access speed and multitasking capabilities. SmartDV offers a complete and scalable solution for DDR Controller IP. SmartDV’s DDR Controller design IP core is highly customizable to optimize design area, power, and performance for both ASIC and FPGA flows, providing flexibility to adapt to specific design requirements.
