Abstract: A nonvolatile (NV) memory device includes an NV storage media and a storage controller to control access to the NV storage media. In response to a host read request, the storage controller can determine if the NV storage media is in a stable Vt (threshold voltage) state. If the NV storage media is in a stable Vt state, the storage controller can perform a reset read operation prior to servicing the host read request. A reset read is a read operation that does not produce data to send back to the host. The reset read operation is a dummy read that puts the NV storage media into a transient Vt state, which has lower risk of read disturb.

Abstract: Generally, this disclosure provides systems, devices, methods and computer readable media for secure control of access control enablement and activation on self-encrypting storage devices. In some embodiments, the device may include a non-volatile memory (NVM) and a secure access control module. The secure access control module may include a command processor module configured to receive a request to enable access controls of the NVM from a user, and to enable the access controls. The secure access control module may also include a verification module configured to verify a physical presence of the user. The secure access control module may further include an encryption module to encrypt at least a portion of the NVM in response to an indication of success from the verification module.
