The subject matter described herein relates to a file system with adaptive flushing for an electronic device. The file system keeps data in memory much longer and its policy for flushing in-memory write cache to storage is application-aware and adaptive. More specifically, what parts of the cached data are ready for flushing could be determined according to the access characteristic of an application. In addition, when to do flushing can be selected flexibly at least partly based on user input interactions with an application of the electronic device or with the electronic device. Further, a multi-priority scheduling mechanism for scheduling data units that are ready to be flushed could be employed, which ensures fairness among applications and further improves flushing performance.

A memory module includes a plurality of main memory groups each suitable for storing user data and related ECC data; a cache memory group suitable for caching the user data of one among the main memory groups; an access controller suitable for accessing the main memory groups when user data to be accessed is not cached in the cache memory group; and an ECC unit suitable for performing an ECC operation for user data stored or to be stored in the main memory groups during an access operation for the user data stored or to be stored in the main memory groups.

Method and system are provided for object caching with mobility management for mobile data communication. The method may include: intercepting and snooping data communications at a base station between a user equipment and a content server without terminating communications; implementing object caching at the base station using snooped data communications; implementing object caching at an object cache server in the network, wherein the object cache server proxies communications to the content server from the user equipment; and maintaining synchrony between an object cache at the base station and an object cache at the object cache server.

A data access system including a processor and a storage system including a main memory and a cache module. The cache module includes a FLC controller and a cache. The cache is configured as a FLC to be accessed prior to accessing the main memory. The processor is coupled to levels of cache separate from the FLC. The processor generates, in response to data required by the processor not being in the levels of cache, a physical address corresponding to a physical location in the storage system. The FLC controller generates a virtual address based on the physical address. The virtual address corresponds to a physical location within the FLC or the main memory. The cache module causes, in response to the virtual address not corresponding to the physical location within the FLC, the data required by the processor to be retrieved from the main memory.

Embodiments of the present application provide a method, apparatus and system for processing data, the method is applicable to an electronic device, wherein the electronic device is connected to a memory card that has been formatted in a proprietary manner in advance and the memory card includes at least one cold data area. The method includes: obtaining the number C.sub.R of reads for data stored in a target cold data area C stored locally; determining whether the number C.sub.R of reads reaches a preset threshold T.sub.CR for reading failure of cold data; if the number C.sub.R of reads reaches a preset threshold T.sub.CR for reading failure of cold data, transmitting a start address and a end address of the data stored in the target cold data area C to a controller of the memory card, and initializing the number C.sub.R of reads for processing the stored data by the controller according to the start address and the end address.
