a memory, comprising multiple memory pages;

an integrated circuit, converting multiple virtual addresses into multiple physical addresses in sequence; wherein the integrated circuit comprises:

an address remapping unit, prefetching a first physical address corresponding to a first virtual address if a second virtual address exceeds a preset offset, wherein the first virtual address is in a different memory page from the second virtual address, the second virtual address is currently processed, the multiple virtual addresses include the first and second virtual addresses;

wherein the preset offset is set according to latency of reading data from the memory.
