A trim management method for a storage device includes activating, by a processor configured by an application program, a pattern check function of a device driver, requesting, by the processor configured by the application program, a file system to write a file of a specified pattern, converting, by the processor configured by the file system, the file to management unit data of the storage device, transmitting, by the processor configured by the file system, the management unit data to the device driver, checking, by the processor configured by the device driver, whether a data pattern of the management unit data is the same as the specified pattern, and transmitting, by the processor configured by the device driver, a trim command for trimming a storage area corresponding to the management unit data, to the storage device based on results of the checking.

User device including storage device and trim management method thereof

A nonvolatile memory device includes a memory cell array that includes memory blocks, wherein each of the memory blocks includes pages each including memory cells, a row decoder circuit that selects one of the pages from a selected memory block of the memory blocks in a write operation and selects memory cells of a close unit from the selected memory block in a close operation, and a page buffer circuit that writes data into memory cells of a page selected by the row decoder circuit in the write operation and writes dummy data into the memory cells of the close unit selected by the row decoder circuit in the close operation. The close unit includes one or more pages, and, in the close operation, the row decoder circuit adjusts a size of the close unit.

Nonvolatile memory device, storage device including nonvolatile memory device, and method of accessing nonvolatile memory device

A method used by an electronic device receiving a geo-fence service, determines whether a current position of the electronic device, determined using a cellular positioning system (CPS), is located within a first distance from a central point of a geo-fence service area. In response to determining that the current position is located within the first distance, the current position is determined using a Wi-Fi positioning system (WPS) and it is further determined whether the WPS determined current position is located within a second distance from the central point of the geo-fence service area. In response to the determination the current position is located within the second distance, it is determined whether the current position calculated using a global positioning system (GPS), is located within a boundary of a geo-fence service area.

Disclosed is a coordination polymer crystal with porous metal-organic frameworks (MOFs), in which, while a crystal state of the coordination polymer crystal is maintained, an additional material selected from the group consisting of an organic compound, a metal cluster, and an organometallic compound is chemically bonded to the coordination polymer crystal. Therefore it is possible easily adsorb and store more guest molecules regardless of a change in an ambient temperature or pressure due to the chemically bonded additional material.

A display apparatus includes a front casing and a rear casing, a CRT coupled to the front casing and mounted with a degaussing coil, and a main board disposed adjacent to the CRT to transmit electrical signals to the CRT. A base frame receives therein the main board. A frame supporting part, which is positioned in a rear part of the front casing, supports the base frame so as to have an upward angle of inclination in a backward direction. With this configuration, a display apparatus has a visual volume that is reduced to a minimum and the assembly is prevented from tipping forward in the assembling processes.

Disclosed herein is a hot plugging device for optical transceiver modules. The hot plugging device comprises a module housing, latching grooves extended from prescribed positions of both sides of the module housing to one end of the module housing, respectively, sliding members extended in the longitudinal direction of the module housing and linearly movably accommodated in the latching grooves, respectively, and a rotating member rotatably attached to one end of the module housing for engaging ends of the sliding members with corresponding ends of the latching grooves, respectively, while the rotating member is placed at a prescribed angle to the longitudinal direction of the module housing. With the hot plugging device of the present invention, a locking unit of the module housing is easily released, and the release of the locking unit is maintained, whereby the module housing is easily separated from a cage. Also, a working space necessary to separate the module housing from the cage is reduced, whereby many more optical transceiver modules can be mounted. Furthermore, only latching pieces are deformed when the module housing is separated from the cage. Consequently, the present invention has an effect of preventing permanent deformation of the module housing or the cage or damage to the module housing or the cage.
