Abstract: A system includes multiple master devices and at least one memory refresh scheduler. When a master device needs higher priority for memory access, the master device sends a dynamic priority signal to the memory refresh scheduler and in response, the memory refresh scheduler changes its policy for issuing refresh commands.
