An integrated memory controller (IMC) is a component within a computer's central processing unit (CPU) that manages the flow of data to and from the system's memory (RAM). By being built directly into the CPU, the IMC reduces latency and improves performance compared to older systems where the memory controller was a separate chip on the motherboard. IMCs support various memory types and standards, such as DDR4 and DDR5, allowing for faster data access and better overall system efficiency. This integration helps streamline communication between the CPU and memory, enhancing the speed and responsiveness of applications and tasks.
