Abstract: A sustained status accelerating method for a storage device includes: controlling the storage device to receive a sustained status command from the outside; and controlling the storage device to enter the sustained status using a sustained valid page count (SVPC) table in response to the sustained status command so that each of a plurality of blocks constituting the storage device has a value greater than a predetermined valid page count. The SVPC table includes a valid page count with respect to each of the blocks in the storage device.

Abstract: A storage controller configured to control a nonvolatile memory includes a one-time programmable (OTP) memory configured to store a first public key, and a processor configured to, based on a first signature added to a firmware image including a host authentication public key being verified using the first public key, receive a storage command including at least one second public key and a first host authentication signature for the at least one second public key and store the at least one second public key in the OTP memory based on the first host authentication signature being verified using the host authentication public key.
