What is the role of the memory controller in a computer system?

The memory controller in a computer system is responsible for managing and controlling the flow of data between the central processing unit (CPU) and the computer's memory. It ensures that data is properly stored and retrieved from the memory modules, and coordinates the timing and synchronization of data transfers. The memory controller also handles tasks such as error correction, memory addressing, and optimizing memory access for improved performance. Overall, its role is to facilitate efficient and reliable communication between the CPU and memory subsystem.
