A flash controller has a flash interface accessing physical blocks of multi-level-cell (MLC) flash memory. An Extended Universal-Serial-Bus (EUSB) interface loads host commands into a command queue where writes are re-ordered and combined to reduce flash writes. A partial logical-to-physical L2P mapping table in a RAM has entries for only 1 of N sets of L2P mapping tables. The other N−1 sets are stored in flash memory and fetched into the RAM when a L2P table miss occurs. The RAM required for mapping is greatly reduced. A data buffer stores one page of host write data. Sector writes are merged using the data buffer. The data buffer is flushed to flash when a different page is written, while the partial logical-to-physical mapping table is flushed to flash when a L2P table miss occurs, when the host address is to a different one of the N sets of L2P mapping tables.

The invention discloses a software upgrading method and a software upgrading device which are used for solving the problems that update of application software of a mobile terminal occupies large network flow and is complex and inconvenient. Function codes finishing concrete program functions in a main program are extracted and packaged to form an implementation class, a call interface is abstracted, and the main program calls the implementation class through the call interface so as to finish the concrete program functions. When the function codes need updating, the main program acquires an implementation class of a new version, and the implementation class of an old version is replaced with the implementation class of the new version. When the software is updated, users only need to download code files of part of logic from a server so as to replace original code logic, and because updated content is only a subset of overall program codes, the occupied network flow is small. Under a silent update mode, the software automatically finishes an upgrading process during the software using process of the users, and accordingly the aim of silent update is achieved.
