A storage device includes a nonvolatile memory device including a plurality of nonvolatile memories; a controller configured to allocate write blocks of the nonvolatile memory device to a plurality of streams provided from an outside; and a buffer memory configured to store a result of allocation of the write blocks to the plurality of streams, wherein the controller is further configured to reallocate the write blocks of the nonvolatile memory device to the plurality of streams based on the result of allocation stored in the buffer memory.

Storage device, storage system, and operating method thereof capable of dynamically allocating write blocks to a stream

A memory storage device is capable of improving reliability of a memory system. The memory storage device comprises a memory controller, and a non-volatile memory connected to the memory controller. A method includes receiving, by the memory controller, a command from a host device, the command requesting lost LBA (logical block address) information resulting from a system shutdown of the memory storage device, in response to the command, providing, by the memory controller, the lost LBA information, and receiving, by the memory controller, recovered data corresponding to the lost LBA information, wherein the lost LBA information includes at least one of the number of LBAs lost by system shutdown, an LBA list lost by system shutdown, and deletion of a previous LBA list lost by system shutdown.

Memory storage device, method for operating the storage device and method for operating a host device

A storage device may include a monitoring module which monitors a characteristic degradation rate of a plurality of blocks included in a cell array of a nonvolatile memory; a group management module which designates the plurality of blocks as one or more groups, on the basis of a monitoring result of the monitoring module; a refresh period management module which determines refresh periods for each of the one or more groups; and a processor which performs refresh on the one or more groups in accordance with the determined refresh periods.

Storage device and method for operating storage device

A memory device and a dynamic garbage collection method thereof are provided. The method includes receiving a minimum operating speed, ascertaining a reference valid page count ratio (VPC), using a maximum operating speed, the minimum operating speed, and a garbage collection speed, the reference VPC ratio being ascertained by the following formula 1 and determining whether to perform a garbage collection, using the reference VPC ratio and a current average VPC ratio. &#x3c;Formula 1&#x3e; Vr=Gp (Jp&#x2212;Mp)/(Jp*Mp+(Gp*(Jp&#x2212;Mp))) Here, Vr is the reference VPC ratio, Gp is the garbage collection speed, Jp is the maximum operating speed, and Mp is the minimum operating speed.

Method of dynamic garbage collection for a memory device based on valid page count (VPC), garbage collection speed, and maximum and minimum operating speeds

Provided are a liquid crystal display module and a method for manufacturing the same. The liquid crystal display module comprises a liquid crystal panel, a backlight unit, a support main, and a top cover. The backlight unit is disposed in rear of the liquid crystal panel. The support main comprises a rectangular frame for laminating and housing the liquid crystal panel and the backlight unit, and a metal cover disposed around an outer sidewall surface and a bottom surface of the rectangular frame. The top cover covers a front edge of the liquid crystal panel, and is combined with a side part of the support main.

Liquid crystal display module and method for manufacturing the same

Provided is a backlight unit that increases brightness and increases uniformity of the brightness. The backlight unit includes a plurality of point light sources. A light guide panel includes a first surface that receives incident light from the point light sources. A second surface is where the lights from the point light sources cross. Prism patterns are formed on the first surface.
