Abstract
A method of decommissioning a solid-state drive including a non-volatile memory media and a controller. Decommissioning is achieved by a disabling command sequences, internal communication channels, and interfaces. A non-volatile memory media is permanently disabled by short circuiting an internal high voltage generator to an electrical ground so that a high voltage cannot be generated for an operation required to access data on the memory media. The short circuit path may be enabled using a one-time programmable element. Further, an ability of a non-volatile memory media interface to initiate a command sequence that is required to access the memory media is disabled, and a status confirmation indicating that the memory media has been disabled is issued. A controller is also permanently disabled by disabling an ability of a flash interface to communicate with the non-volatile memory media so that no commands can be received by the memory media.
