Abstract
A storage device ensures erasure of a first memory device even when the storage device is in an unrecoverable state. The storage device includes the first memory device and a controller. The controller executes operations on the first memory device in response to instructions received from a host coupled to the storage device. The controller may detect when an unrecoverable error occurs when executing instructions and enter an exception handling mode. The controller may also determine if the storage device enters an unrecoverable state and may move into a restricted firmware mode when the storage device enters the unrecoverable state. When in the restricted firmware mode, the controller may load firmware into a second memory device and, upon receiving a sanitize instruction from the host, the controller may execute the firmware in the second memory device to delete data in the first memory device.
