  • Patent number: 12228902
    Abstract: Disclosed is a system for transmitting and receiving safety information, which generates first safety information about a control target and second safety information representing the occurrence or not of an error in the control target by using one microcontroller. The system includes a first slave controller generating first safety information and second safety information by using sensing data obtained from a control target and a master controller receiving the first safety information and the second safety information from the first slave controller through a wireless channel. When an error occurs in the first slave controller, the first slave controller transmits the second safety information to a second slave controller, and the second slave controller transmits the second safety information, received from the first slave controller, to the master controller.

  • Patent number: 11386018
    Abstract: Embodiments of the present disclosure relate to a memory system and an operating method thereof. According to the embodiments of the present disclosure, the memory system may generate a nonce based on a physical address of a target area of a memory device using a cryptographic algorithm, and request the memory device to authenticate the nonce. When the authentication for the nonce succeeds, the memory controller may set an authority to perform a read, write or erase operation on the target area. Through this operation, the memory system can prevent data leakage or damage by a user who has no access authority.
