    Abstract: A storage device includes a memory device and a solid state drive used as a cache memory for the memory device. The solid state drive includes a storage unit including a plurality of nonvolatile memory cells, a memory controller configured to control the storage unit, and a data management unit configured to manage pieces of data, stored in the storage unit, in order of less recent access time. The data management unit may set at least one of the pieces of data, stored in the storage unit, as cold data based on a data access point in time, and may send an internal trim command for the cold data to the memory controller when a valid data ratio of the storage unit is higher than a reference valid ratio. The memory controller may perform an internal trim operation on the cold data.

    Abstract: A wearable electronic device may include: a housing including a front plate, a rear plate, and a side member surrounding an inner space between the front plate and the rear plate, wherein the side member includes at least one portion including an external opening and an inner channel connecting between the inner space and the external opening: an insulating structure inserted into the inner channel; a conductive path partially embedded in the insulating structure, wherein the conductive path includes a first end exposed to the inner space and a second end exposed to the external opening; at least one printed circuit board positioned in the inner space and electrically connected to the first end of the conductive path; a display exposed through the front plate; and a band structure connected to the portion of the housing and configured to be mounted on a portion of a human body. The band structure may include a conductive rod movably inserted into the external opening and electrically connected to the second end of the conductive path, and an electronic component at least partially embedded in the band structure and electrically connected to the conductive rod. Other various embodiments may also exist.

    Abstract: Disclosed is a storage device comprises a non-volatile memory configured to store data; a storage controller configured to determine a time to back up recovery data when a sudden power-off occurs and to perform a data dump operation according to a dump level determined based on the determined time when a user data dump fails; and a power loss protection (PLP) integrated circuit configured to measure at least one of a discharge time or remaining time of an auxiliary power supply when the sudden power-off occurs and to provide at least one of discharge time information or remaining time information to the storage controller, wherein the storage controller is configured to determine a minimum recovery data backup time in case of a user data dump failure using the at least one of the discharge time information or the remaining time information.
