Abstract
A memory system may include: a nonvolatile memory device including a plurality of memory blocks; and a controller for reading data stored in a physical address in response to a read command from a host, the read command including a first logical address, a first physical address corresponding to the first logical address, and a first read count associated with the first physical address, the controller may read first data from a first block corresponding to the first physical address and sends a response to the read command to the host, the response including the first data and updated information relating to the first read count.
Claims20
A memory system, comprising:
- a nonvolatile memory device including a plurality of memory blocks;
- and
- a controller for reading data stored in a physical address in response to a read command from a host, the read command including a first logical address, a first physical address corresponding to the first logical address, and a first read count associated with the first physical address,
- wherein the controller reads first data from a first block corresponding to the first physical address and sends a response to the read command to the host, the response including the first data and updated information relating to the first read count.
A data processing system, comprising:
- a host for sending a read command including a first read count and a first physical address corresponding to a first logical address;
- and
- a memory system including a nonvolatile memory device having a plurality of memory blocks, the memory system being configured to read data from a physical address in response to a read command from a host, the read command including a first logical address, a first physical address corresponding to the first logical address, and a first read count associated with the first physical address,
- wherein the memory system reads first data from a first block corresponding to the first physical address and sends a response to the read command to the host, the response including the first data and updated information of the first read count.
A method for operating a memory system, the method comprising:
- reading data from a block in a non-volatile memory device in response to a read command received from a host, the read command including a first logical address, a first physical address, and a first read count associated with the first physical address;
- and
- sending a response to the read command to the host, the response including the data and information associated with a read count for the block.
