Abstract: A host system configured to communicate with a storage system, including a host flash translation layer (FTL) configured to manage a plurality of blocks included in the storage system, wherein the host FTL includes a block assignment module configured to generate priority information indicating priorities of free blocks from among the plurality of blocks based on erase count values of the free blocks, and wherein the host FTL is configured to assign a free block having a lowest erase count value, from among the free blocks, for a data write operation based on the priority information; a counting circuit configured to count a number of erase operations performed on each of the plurality of blocks; and an interface circuit configured to transmit to the storage system a block address along with an access request to the storage system, the block address indicating a position of the assigned free block.

Abstract: A method of operating a memory system including a memory device, including in response to a write request of a host, storing write data and a physical address received from the host in a buffer; performing a write operation on the memory device based on the write data and the physical address; based on a write error corresponding to the write data occurring, asynchronously providing the host with error occurrence information; and providing the host with the write data having the write error and information used for a recovery from the write error.

Abstract: A method of operating a memory system including a memory device, including reading data from the memory device based on a first physical address received from a host according to a read request received from the host; detecting a read error of the read data; correcting the read data based on the detecting; transmitting the corrected data to the host; asynchronously transmitting to the host an error occurrence signal for the read error; generating information about the read error; transmitting the information about the read error to the host; and rewriting the corrected data based on a second physical address received from the host according to a write request of the host.
