    摘要: A device is presented including a memory controller. The memory controller is connected to a read request queue. A command queue is coupled to the memory controller. A memory page table is connected to the memory controller. The memory page table has many page table entries. A memory page history table is connected to the memory controller. The memory history table has many page history table entries. A pre-calculated lookup table is connected to the memory controller. The memory controller includes a memory scheduling process to reduce memory access latency.
