摘要： A storage system includes a storage medium configured to store data and a buffer memory configured to buffer data to be written to the storage medium. The storage system further includes a controller configured to selectively transfer the buffered data to the storage medium responsive to an invalidity indicator received from an external source. For example, the invalidity indicator may comprise unwrite information received from an external source, e.g., information that indicates that selected buffered data corresponds to deleted file data.

摘要： A storage device includes a host interface, a buffer memory, a storage medium, and a controller. The host interface is configured to receive storage data and an invalidation command, where the invalidation command is indicative of invalid data among the storage data received by the host interface. The buffer memory is configured to temporarily store the storage data received by the host interface. The controller is configured to execute a transcribe operation in which the storage data temporarily stored in the buffer memory is selectively stored in the storage medium. Further, the controller is responsive to receipt of the invalidation command to execute a logging process when a memory capacity of the invalid data indicated by the invalidation command is equal to or greater than a reference capacity, and to execute an invalidation process when the memory capacity of the invalid data is less than the reference capacity. The logging process includes logging a location of the invalid data, and the invalidation process includes invalidating the invalid data.

摘要： A system for processing a read request for maximizing host read performance in a flash memory-based storage device is provided. The system for processing the read request solves a bottleneck phenomenon caused by a processor by adding an independent automatic read request processor, different from a conventional system in which a processor of a storage device processes the read request. Also, when processing the read request, a storage device using a write buffer may control a process of merging data of the write buffer and a flash memory and transmitting the data to a host based on a descriptor array, thereby minimizing processor overhead.

摘要： Disclosed are a system and method for controlling a flash memory using a descriptor array, which may maximize a performance of a flash memory based-storage system. The system includes a descriptor array receipt unit for receiving, from a processor, a descriptor array including, at least one descriptor corresponding to at least one operation; and a flash memory control unit for verifying the descriptor included in the descriptor array and executing a flash memory control command included in the verified descriptor, wherein the flash memory control unit executes the flash memory control command independent from the operation of the processor.
