Abstract

Keys are generated at a memory device with a period of time elapsing between generation of each key. A request is received from a memory controller for the most recently generated key. The memory device communicates the first key to the memory controller. Access to nonvolatile memory on the memory device is locked. An unlock command with a second key is received from the memory controller. The memory device determines that the second key matches the first key and unlocks access to the nonvolatile memory in response.
