Apparatuses and methods related to memory authentication. Memory devices can be authenticated utilizing authentication codes. An authentication code can be generated based on information stored in a fuse array of the memory device. The authentication code can be stored in the memory device. The stored authentication code can be compared to a captured authentication code based on fuse array information broadcast to memory components of the memory device. The authenticity of the memory device can be determined based on the comparison and can result in placing the memory device in an unlocked state.

Memory authentication

Apparatuses and methods related to detecting synchronization between multiple devices. The security of a device may be compromised if the device receives commands from unauthorized sources. A state of a device can be affected by the commands the device receives. A different device can determine whether there is synchronicity between device and the different device to determine whether the security of the device may have been compromised.

Device intrusion detection via variable code comparison

Apparatuses and methods related to memory disablement for memory security. Disabling the memory for memory security can include, responsive to receiving a trigger signal, provide a voltage, which may be in excess of an operating or nominal voltage, to the access circuitry. The voltage may thus be sufficient to render the access circuitry inoperable for accessing data stored in the memory array.

Memory disablement for data security

Apparatuses and methods related to authenticating memory. Memory devices can be authenticated utilizing authentication codes. An authentication code can be generated based on information stored in a fuse array of the memory device. The authentication code can be compared to an externally provided authentication code to authenticate the memory device. The memory device may be authenticated to ensure that the memory device is not a security threat.
