Abstract: Various flash management techniques may be described. An apparatus may comprise a processor, a flash memory coupled to the processor, and a flash management module. The flash management module may be executed by the processor to receive a write request to write data to the flash memory, write a first control sector with a sequence number to the flash memory, and write the sequence number, an address for a logical sector, and data to at least one physical sector corresponding to the logical sector of the flash memory. Other embodiments are described and claimed.

Abstract: Flash memory is accessed via mapping tables comprising a master mapping table and at least one secondary mapping table. The master mapping table contains indexes to the secondary mapping tables. The secondary mapping tables contain indexes to locations in the flash memory. The mapping tables are maintained in the flash memory. Upon initialization subsequent a safe power shutdown, the master mapping table is cached and secondary mapping tables are cached as needed. Upon initialization subsequent an unsafe power shutdown, the mapping tables are constructed in accordance with a multiple-phase process. In an example embodiment, the multiple-phase process comprises locating all the secondary mapping tables stored in the flash memory, determining which secondary mapping tables are valid, determining which secondary mapping tables are invalid, determining which sectors of the flash memory are free, and constructing the master mapping table and the secondary mapping tables from this information.

Abstract: Various flash management techniques may be described. An apparatus may comprise a processor, a flash memory coupled to the processor, and a flash management module. The flash management module may be executed by the processor to receive a write transaction request to write data to a flash memory, and write the data to a set of multiple discontiguous logical sectors corresponding to a set of physical sectors of the flash memory in a single atomic operation. Other embodiments are described and claimed.

Abstract: Described is a system and method in which software updates in the form of self-contained, secure entities are applied to an embedded device's non-volatile storage in a failsafe manner. Various types of software updates may be applied, and updates may contain executable code and/or data. Following a reboot, an initial program loader determines an update mode, and if updating, boots to a special update loader. The update loader processes update packages to apply the updates. Kernel partition, system partition and reserve section updates may be updated with entire files or binary difference files, with failure handling mechanisms are provided for each type of update. Updates may be simulated before committing them. Updates may be relocated in memory as appropriate for a device.
