Method of Dynamic Channel Switch by Hypervisor

A memory control method for a computing system, the computing system comprising a memory controller, a central processing unit (CPU), a random access memory (RAM), the memory control method comprising:

• the memory controller determining if the computing system is in a low power mode;
• if the memory controller detects at least one m-channel regions of the RAM has been accessed, the memory controller sending an interrupt to a hypervisor of the CPU;
• the CPU performing page migration to move data in at least one m-channel region of the RAM to at least one n-channel region of the RAM, where m>n;
• and
• after completing the page migration, the CPU notifying the memory controller completion of the page migration.
