摘要:
An apparatus usable with a flash memory as storage and a method of operating the same are provided, which can provide an optimized architecture to a flash memory through combination of a flash transition layer (FTL) with a database. The apparatus includes a flash memory, a device driver to manage a mapping table between logical addresses and physical addresses in accordance with a data operation in the flash memory, and a control unit to perform data recovery of the flash memory by requesting the mapping table through an interface provided by the device driver.

An apparatus for preventing data loss of a nonvolatile memory device and a method thereof are presented The apparatus includes a nonvolatile memory including a memory cell which writes bit information to a first page and a second page included in a first block using plural states which are implemented using at least 2 bits, and a data-processing unit which writes the bit information of the first page to a second block in the nonvolatile memory while the bit information is written to the second page after the bit information is written to the first page.
摘要:
An apparatus and a method of optimizing queries through scheduling User Defined Operators (UDOs) in a Data Stream Management System (DSMS), are provided. The apparatus includes a query optimizer configured to receive queries, each of the queries including the UDOs and data streams subject to respective operations of the UDOs, and group the data streams and UDOs into scheduling units, each of the scheduling units including one of the data streams and one of the UDOs. The apparatus further includes a scheduler configured to schedule an execution order in which the scheduling units are executed.
