DDR4/3, LPDDR5x/5/4x/4 Memory Controller IP

Overview

OPENEDGES, the memory system IP provider, including DDR memory controller, DDR PHY, on-chip interconnect, and NPU IP together as an integrated solution or independent IP. They are tightly combined to bring synergy for high performance and low latency. OPENEDGES' integrated IP solutions are market and silicon-proven, featuring advanced architectures and proprietary technologies that enable customers to shorten their design and verification processes.

OMC – LPDDR5x/5/4x/4/3, DDR4/3 Memory Controller is a small & highly configurable IP. It provides high performance through advanced memory controller design based on proprietary out-of-order scheduling algorithms and high-speed implementation techniques. Demand for more DRAM bandwidth is getting stronger than ever in a quest to improve user experiences (e.g., higher image resolution). Given the limited amount of physically available DRAM bandwidth, highly efficient memory controller IP is becoming a very critical issue everywhere. With our OMC – LPDDR5/4 Memory Controller, SoCs can save a significant amount of area & power consumption and meet next-generation SoC’s DRAM bandwidth requirements.
