Abstract: A peripheral component interconnect (PCI) device includes a first memory which includes a plurality of page buffers, a base address register which includes a plurality of base addresses, and a first address translation unit which translates each of the plurality of base addresses to a corresponding one of a plurality of virtual addresses. A map table includes a plurality of map table entries each accessed in correspondence to each of the plurality of virtual addresses, and maps each of the plurality of virtual addresses onto a physical address of physical addresses of the plurality of page buffers. The first address translation unit translates each of the plurality of virtual addresses to a corresponding one of the physical addresses using the map table.
