Abstract: A redundant array of independent disks (RAID) storage device including; a memory device including first memory devices configured to store at least one of data chunks and corresponding parity (data chunks/parity) and a second memory device configured to serve as a spare memory region, and a RAID controller including a RAID internal memory configured to store a count table and configured to control performing of a rebuild operation in response to a command received from a host, wherein upon identification of a failed first memory device, the RAID controller accesses used regions of non-failed first memory devices based on the count table and rebuilds data of the failed first memory device using the second memory device.

Abstract: A system includes a transmission device and a reception device that are connected through a link. The reception device includes a reception buffer configured to receive and store transaction layer packets and a reception flow controller configured to generate flow control packets by monitoring an occupation state of the reception buffer. The transmission device includes a transmission buffer, a transmission flow controller and a dynamic frequency controller. The transmission buffer stores pending transaction layer packets to be transferred to the reception device. The transmission flow controller controls a flow of transaction layer packets to be transferred to the reception device based on the flow control packets received from the reception device. The dynamic frequency controller controls a frequency of an internal clock signal of the transmission device by monitoring a state of the transmission buffer and a state of the transmission flow controller.

Abstract: A storage system communicates with a host system and includes a storage device including storage medium divided into a plurality of blocks including high reliability blocks and reserve blocks, and a controller. The controller provides the host system with block information identifying the high reliability blocks among the plurality of blocks, receives a block allocation request from the host system, wherein the block allocation request is defined with reference to the block information and identifies at least one high reliability block to be used to store metadata, and allocates at least one high reliability block to a meta region in response to the block allocation request. The controller includes a bad block manager that manages an allocation operation performed in response to the block allocation request, and a repair module that repairs an error in metadata stored in one of the high reliability blocks.
