Patent ID: 7062627

Claim:
A computer system supporting a virtual memory system, said computer system comprising, a processor, a first main memory which said processor accesses, a non-volatile storage storing first memory size information regarding said first main memory and second memory size information regarding a second main memory to be hot plugged, and a housing including said processor, said first main memory and said non-volatile storage, wherein said processor has an address translating unit translating virtual addresses and physical addresses, said processor outputs physical addresses representing a region of said first main memory, wherein said first main memory has at least a part of address translation information of said first main memory and has a first region in which address translation information for said second main memory is to be stored, wherein said processor has a unit translating logical-physical addresses, accesses said address translation information for said first main memory and generates physical addresses, and wherein said first main memory stores said address translation information for said first main memory in a top priority region of interrupt handling and assigns said first region in said top priority region.
