摘要： A method of operating a storage device using a host memory buffer of a host includes: recording information on HMB addresses on the host memory buffer, respectively corresponding to a plurality of read requests for the host memory buffer, in an address information table when the plurality of read requests are required; transmitting the plurality of read requests to the host memory buffer, regardless of a response of the host memory buffer; receiving a plurality of pieces of read data, respectively corresponding to the plurality of read requests, from the host memory buffer; detecting an error of each of the plurality of pieces of read data; and updating the address information table based on a result of the error detection.

摘要： A memory system includes a memory controller and a memory device including a plurality of dies, each die including a plurality of blocks. A plurality of commands are configured to control the memory device in units of super blocks. During a first time interval, a first erase operation is performed on a first-first block among the first-first block to a first-Mth block, and a first program operation is performed on a second-first block to a second-Mth block, based on the first commands. During a second time interval, a second erase operation is performed on a first-second block among the first-first block to the first-Mth block, and a second program operation is performed on the first-first block and one or more blocks among the second-first block to the second-Mth block, based on the second commands.
