DDR3/3L Controller IP
Design IP
Overview

SmartDV’s DDR3/3L Controller IP is a silicon-proven, high-performance solution designed to enable efficient memory interfacing for a wide range of applications, from consumer electronics to high-end computing and networking. It supports JEDEC-standard DDR3 and DDR3L SDRAM protocols, delivering reliable, high-speed data throughput with low latency and robust command scheduling.

Designed for flexibility, the IP core is highly configurable to meet specific design requirements, supporting both ASIC and FPGA implementations while optimizing for area, power, and performance. With advanced features such as multi-port support, command reordering, and low-power operation modes, the controller ensures seamless integration into complex SoC designs while maintaining compliance with industry standards.
