Claim 3:
4. The controller according to claim 3, wherein when the size information in the first page table entry increases, the controller is configured to calculate a base physical frame number by changing lower M bits of the physical frame number in the first page table entry to the second state,
wherein when the physical frame number in the first page table entry is the same as the base physical frame number, the controller is configured to maintain the increased size information, and when the physical frame number of the first page table entry is not the same as the base physical frame number, the controller is configured to decrease the increased size information and change the valid information in the first page table entry to a previous value, and
wherein M is (log2(a number of bits in the valid information in the first page table entry)×(the increased size information+1)).
