Summary:A memory controller, a memory system and a method of operating the memory controller are disclosed. A memory controller includes a CPU selecting a memory bank, a memory storing a first extended address associated with the selected memory bank, and a memory management unit (MMU) cloning the first extended address and storing the cloned first extended address as a second extended address. The MMU includes snoop logic that stores a first address corresponding to the first extended address, receives a second address from the CPU, compares the first address with the second address, and provides an update signal in response to the comparison of the first address and second address. The MMU also includes a cloning register that updates the second extended address with input data received from the CPU in response to the update signal. The memory and MMU are both directly connected to the CPU via a low latency interface.
