In a method of operating a storage device, the storage device includes a plurality of memory blocks. A data write request and target data to be written are received. Using a data classifier, such as a neural network model, the target data is assigned to a stream selected from a plurality of streams based on a data property of the target data. The target data is written into a memory block assigned to a stream selected for assignment of the target data, such that target data that has been assigned to a stream are written into the one or more memory blocks assigned to the stream.

Method of operating storage device with a plurality of streams using a data classifier, storage device performing the same and storage system including the same

A memory controller including: a memory configured to store first and second mapping tables; and a hashing module configured to receive a command including a first key from a host and retrieve a first physical address corresponding to the first key by using the first and second mapping tables, wherein the first mapping table is configured to store first region information about a first region corresponding to a partial region of the first key, the first region including at least one segment, and the second mapping table is configured to store a plurality of segments, wherein each segment includes a plurality of hash entries, the plurality of segments are grouped into a plurality of regions, and each of the plurality of hash entries stores a tag corresponding to a key and a physical address corresponding to the key,

Memory controller including mapping tables to efficiently process an iteration command and a method of operating the same

Garbage collection is performed according to an estimated number of valid pages. A storage device estimates a valid page count at a future time based on a valid page count at each of past time steps and a present time step using a neural network model and selects a victim block that undergoes the garbage collection from memory blocks based on an estimated valid page count. A memory block having a lowest estimated valid page count or having an estimated valid page count having a maintaining tendency is selected as the victim block or a memory block having the estimated valid page count having a decreasing tendency is excluded from selecting the victim block.

Storage device, method and non-volatile memory device performing garbage collection using estimated number of valid pages

A pop-up device of a fuel door may include a fuel door configured to be rotatably provided on one side of a vehicle body to open or close a fuel inlet and have a locking portion formed on an internal side thereof, a cable housing configured to be disposed on an internal side of the fuel inlet and include a stopper connected to a cable, and a catch configured to be formed on one end portion of the cable housing and open or close the fuel door by a reciprocating movement of the pop-up rod.

Pop-up device of fuel door

A structure for opening and closing a fuel door may include the main body e rotatably coupled to the vehicle body, and having a binding portion formed on a surface of the main body, a housing formed in a pipe shape and mounted on the vehicle body, and having a plurality of openings at a side of the housing, a pop-up rod having a fastening portion formed at an upper end of the pop-up rod and engaged with the binding portion, a first spring mounted to allow the pop-up rod to move upward toward the main body, and a locking rod which has a first end inserted into a fixing groove formed at a side of the pop-up rod when the locking rod moves forward, to restrict a sliding movement of the pop-up rod, in which the locking rod may be formed in a dual fork shape.

Structure for opening and closing fuel door

A structure of a hood latch may include a base plate attached to a front side of a vehicle body having a fixation groove to allow a striker coupled to a hood to enter the fixation groove, a latch in which a first end is hinge-coupled to a first side of the base plate and a hook is formed at a second end of the latch so as to hook the striker, a pawl in which a first end is hinge-coupled to a second side of the base plate, a second end is connected to and elastically supported by a second spring, and an engagement protrusion is provided to restrict movement of the latch, a bracket to be rotated in a clockwise and anti-clockwise direction, and an actuator connected to a first side of the bracket to move the bracket in left and right directions.
