Abstract: A storage device performing a secure erase and an operating method thereof are provided. The storage device may include a controller configured to control a non-volatile memory device including a plurality of blocks. The controller includes a secure erase control logic configured to control a secure erase operation on the plurality of blocks and perform a control operation in response to a secure erase request from a host with respect to a first block among the plurality of blocks such that the secure erase operation on the first block is skipped based on a result of determining at least one selected from a secure erase state and/or a deterioration state of the first block.

Abstract: A method of operating a controller for controlling a memory device that comprises a plurality of memory cell blocks including outputting block address information based on reliability information for each of the memory cell blocks, providing a patrol read command to the memory device, and controlling the memory device to perform the patrol read operation in response to the patrol read command wherein the block address information comprises an order of the patrol read operation for the memory cell blocks based on the reliability information may be provided.

Abstract: A storage device includes a controller configured to control a non-volatile memory device(s) having a plurality of memory blocks therein. The controller includes secure erase control logic configured to: (i) control secure erase operations on the plurality of memory blocks in response to a secure erase request received from a host, and (ii) set flags corresponding to the plurality of memory blocks such that a first flag corresponding to a first memory block, which has undergone at least two of the secure erase operations, has a first value. Adaptive control logic is provided, which is configured to change at least one operating condition associated with a write operation and/or read operation directed at the first memory block, in response to detecting that the first flag has the first value.

Abstract: The present invention relates to a method and apparatus for selectively and retroactively recording only a music section out of radio broadcast content. According to the present invention, there is provided a method for selectively and retroactively recording only a music section out of radio broadcast content, comprising the steps of (a) detecting a start point of the music section; (b) temporarily recording the music section from the start point in a buffer memory; (c) detecting a command to record the music section placed by a user; and (d) transferring the music section recorded in the buffer memory to a semi-permanent memory.
