Memory Controller

Overview

Delivers excellent performance in addition to high utilization and ultra-low latency, achieved by its proprietary out-of-scheduling algorithm and high-speed implementation. Designed to address the needs of next-generation SoCs, the OMC saves a significant amount of area and power while supporting the highest levels of the DRAM bandwidth.
