Abstract
A storage device and method for enabling hidden functionality are provided. In one embodiment, a storage device is provided comprising an interface a memory, and a controller. The controller is configured to receive a series of read and/or write commands to the memory from the host device. If the series of read and/or write commands received from the host device matches an expected pattern of read and/or write commands, irrespective what data is being read or written by those commands, the controller enables a special functionality mode of the storage device. Other embodiments are possible, and each of the embodiments can be used alone or together in combination.
