Abstract

A mobile device (100) includes a processing device (140), a random access memory, RAM, (150) and an embedded mass storage device (160). A first interface (IF1) is provided between the processing device (140) and the RAM (150). The first interface (IF1) supports access of the processing device (140) to the RAM (150). The mass storage device (160) includes a controller (170) and a non-volatile flash memory (180). A second interface (IF2) is provided between the controller (170) and the flash memory (180). The second interface (IF2) supports access of the controller (170) to the flash memory (180). A third interface (IF3) is provided between the controller (170) and the processing device (140). The third interface (IF3) supports access of the controller (170) to the RAM (150).

Description

technical field [0001] Embodiments of the present invention relate to mobile devices with embedded mass storage devices and methods of storing data in mobile devices. Background technique [0002] Flash memory-based mass storage devices are frequently used in mobile devices, for example as embedded mass storage for user data and / or application data. Examples of such embedded mass storage devices are devices known as eMMC (Embedded Multimedia Card) or UFS (Universal Flash Memory) as specified for example in JEDEC standards JESD84-B451, JESD220A or JESD223A. [0003] The controllers of these embedded mass storage devices are often provided with complex functions for managing the storage of data in the flash memory. To perform these functions, embedded mass storage devices may need to be equipped with a large amount of random access memory (RAM). However, this adds cost and complexity to the embedded mass storage device. Contents of the invention [0004] Accordingly, ther...
