1. An electronic device connectable to a host, the electronic device comprising:
a nonvolatile memory that includes blocks; and
a controller electrically connected to the nonvolatile memory, wherein
when the electronic device is connected to the host, the controller is configured to transmit first information to the host,
the first information indicates a first logical address range and second information about a cold block,
the first logical address range corresponds to cold data stored in the nonvolatile memory,
the cold block includes the cold data,
the controller is configured to determine the second information about the cold block based on an amount of valid data in the cold block, and
the second information about the cold block includes a processing amount for turning the cold block into a block to which data is writable.
