Abstract
Various embodiments include methods and apparatuses for managing multiple memories on a multi-slot communication 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 single contiguous combined memory. Associations of physical and virtual addresses may be stored on the multi-slot communication device. A single memory access request to the single contiguous combined memory may be made using the virtual addresses, translated into multiple memory access requests for the individual memories using the physical addresses. Memory accesses requests to the single contiguous combined memory may be made using a variety of communications protocols and translated such that at least one of the multiple memory access requests for the individual memories is made using USB communications protocols.
