Abstract:
Memory devices, systems including memory devices, and methods of operating memory devices are described, in which self-lock security may be implemented to control access to a fuse array (or other secure features) of the memory devices based on a predefined event associated with the memory device operation. The predefined event may include an operating parameter of the memory device, one or more commands directed to the memory device, or both. The memory device may monitor the predefined event and determine that the predefined event satisfies a threshold. The threshold may be related to a time elapsed since the predefined event has occurred or a certain pattern in the one or more commands. Subsequently, the memory device may disable a circuit configured to access the fuse array based on the determination such that an access to the fuse array is no longer allowed.
