ABSTRACT:
An address converter for converting logical addresses of a program to physical addresses of a memory device comprises a first address converter having entries corresponding to the logical addresses of the program on a 1 : 1 basis. The first address converter stores physical addresses corresponding to the logical addresses. Each entry of the first address converter has data indicating whether or not the memory area of the memory device corresponding to physical addresses stored in such entry is commonly used for applications. A second address converter has unique entries, each commonly selected by any of the logical addresses corresponding to each memory area of the memory device commonly used. The second address converter stores physical addresses corresponding to the memory areas of the memory device commonly used. The entry of the second address converter is indexed by a physical address stored in an entry of the first address converter, which entry of the first address converter includes data indicating that the corresponding memory area is commonly used.
