An operating method of a storage device which includes a nonvolatile memory and a memory controller configured to control the nonvolatile memory, may include tracking a clock signal; entering a vendor mode of the storage device when the clock signal corresponds to a vendor pattern; and maintaining a normal mode of the storage device when the clock signal does not correspond to the vendor pattern, wherein, in the normal mode, a command received from an external host device is executed according to a first rule, and wherein, in the vendor mode, the command received from the external host device is executed according to a second rule different from the first rule.

Storage device and operating method of storage device

A management method for a memory system executes a first memory system management sequence upon determining that the memory system was normally powered off, and a second sequence upon determining that the memory system was abnormally powered off. The first sequence allows immediate execution of a program operation at a valid data page location extracted from stored metadata, while the second sequence allows execution of a program operation only after programming dummy data to at least one erroneous page.
