The various embodiments include methods and apparatuses for providing multiple memories on a multi-slot communication device or on a multi-slot communication device and a wireless device as a single, contiguous, combined memory. The memories may include various types of universal serial bus (USB) and/or universal integrated circuit card (UICC) memories. Ranges of physical addresses of portions of each memory may be associated with a range of virtual addresses of the combined memory. The associations of physical and virtual addresses may be stored on the multi-slot communication device. A single memory access request to the combined memory may be made using the virtual addresses, then translated into multiple memory access requests for the individual memories using the physical addresses. Providing memory access requests to a memory on the wireless device may be accomplished by connecting to the memory on the wireless device over a wireless network by the multi-slot communication device.
