A portion of a nonvolatile memory is partitioned from a main multi-level memory array to operate as a cache. The cache memory is configured to store at less capacity per memory cell and finer granularity of write units compared to the main memory. In a block-oriented memory architecture, the cache has multiple functions, not merely to improve access speed, but is an integral part of a sequential update block system. Decisions to write data to the cache memory or directly to the main memory depend on the attributes and characteristics of the data to be written, the state of the blocks in the main memory portion and the state of the blocks in the cache portion.

The cache memory is configured to store at less capacity per memory cell and finer granularity of write units compared to the main memory. In a block-oriented memory architecture, the cache has multiple functions, not merely to improve access speed, but is an integral part of a sequential update block system. The cache memory has a capacity dynamically increased by allocation of blocks from the main memory in response to a demand to increase the capacity. Preferably, a block with an endurance count higher than average is allocated. The logical addresses of data are partitioned into zones to limit the size of the indices for the cache.

In a block-oriented memory architecture, the cache has multiple functions, not merely to improve access speed, but is an integral part of a sequential update block system. Decisions to archive data from the cache memory to the main memory depend on the attributes of the data to be archived, the state of the blocks in the main memory portion and the state of the blocks in the cache portion.

According to at least one embodiment, a data storage system is provided. The data storage system includes memory, at least one processor in data communication with the memory, and a deduplication director component executable by the at least one processor. The deduplication director component is configured to receive data for storage on the data storage system, analyze the data to determine whether the data is suitable for at least one of summary-based deduplication, content-based deduplication, and no deduplication, and store, in a common object store, at least one of the data and a reference to duplicate data stored in the common object store.

A magnetic recording medium having a magnetic layer with an L₁₀ structure and an easy magnetization axis lying about 35° out-of-plane of the magnetic layer is disclosed. This medium has very high coercivity (Hc) and anisotropy field (Hk), giving rise to improved thermal stability. Combined with improved writability of the canted magnetic easy axis, this media enables improved recording signal-to-noise ratio (SNR).

The invention discloses a database writing system and a database writing method. The system at least comprises a control module, a thread pool, a buffer memory module, a timing scanning module and an asynchronous information processing module. The control module is used for recording writing requests into subtask queues of the tread pool when receiving the writing requests, writing task data into the buffer memory module and transmitting asynchronous requests according to scanning results of the timing scanning module. The thread pool comprises a plurality of subtask queues, and each subtask queue saves a plurality of tasks. The buffer memory module is used for saving the task data. The timing scanning module timely scans the subtask queues in the thread pool to judge whether releasing time comes, judge whether one subtask queue meets the releasing time or not and conduct grouping on data in the subtask queue. The asynchronous information processing module processes the asynchronous requests, receives parameter information of the subtask queues in the releasing process, records the queue tasks and writes corresponding data into a database after monitoring new tasks. By means of the database writing system and database writing method, orderly, efficient and blocking type database writing can be achieved.

An object of the present invention is to provide an e-mail editing device having excellent operability, in particular, an e-mail editing device capable of switching and displaying related e-mails. A display processor simultaneously displays a message editing screen for displaying an edition mail and a mail reference screen for displaying a reference mail for reference. A reference processor copies an object in the reference mail to a temporary storage. An editor pastes the object to an edition mail. A mail search portion searches for an e-mail in a memory on the basis of the reference mail. When a user performs a mail switching operation, the reference mail is switched to a searched e-mail for display.

The invention discloses a DBC file parsing and message analyzing method based on a regular expression. In the method, a content of a DBC file is parsed through a processing method of matching and substituting of the regular expression, the parsed DBC data is used for analyzing a CAN message acquired from a finished automobile, a corresponding CAN network message block in the DBC file and signals contained in the CAN network message block are found according to a message ID, actual data is obtained through data type, start bit, bit length, offset, proportionality coefficient and parsing type ofthe CAN network message block, and the data is stored in a corresponding file. The method provided by the invention has excellent effects of being simple and highly expandable, not only being capableof performing CAN message parsing, but also being capable of performing acquisition and calibration of use completed data of protocols of XCP and CCP.
