Abstract

The present invention relates to a method, a memory adapter and a system for handling data in a fixed memory of a mobile device. The inventive concept provides non-volatile memory as a kind of cache memory for accessing mass storage, wherein the fixed memory comprises at least one non-volatile memory and at least one mass storage. An advantage of the invention is that in case of an unexpected power failure, the corruption of data can be avoided, which is particularly important when operating mobile devices. Further, the non-volatile memory acting as a cache memory increases the access speed of the mass storage. Moreover, from the terminal point of view, the access to the mass storage is simplified since data is only stored and retrieved from the non-volatile memory independent of the kind of mass storage combined with the non-volatile memory.
