Abstract: A method includes, responsive to a SET command associated with a key-value store, concurrently updating the key-value store maintained on a non-persistent memory device of a memory sub-system and a mirror of the key-value store maintained on a persistent memory device of the memory sub-system. The method further includes responsive to a GET command associated with the key-value store, retrieving a value of a key from the key-value store maintained on the non-persistent memory device.

Abstract: The exemplified methods and systems provide hardware-circuit-level encryption for inter-core communication of photonic communication devices such as photonic network-on-chip devices. In some embodiments, the hardware-circuit level encryption uses authentication signatures that are based on process variation that inherently occur during the fabrication of the photonic communication device. The hardware level encryption can facilitate high bandwidth on-chip data transfers while preventing hardware-based trojans embedded in components of the photonic communication device such as PNoC devices or preventing external snooping devices from snooping data from the neighboring photonic signal transmission medium in a shared photonic signal transmission medium. In some embodiments, the hardware-circuit-level encryption is used for unicast/multicast traffic.
