  • Patent number: 11309048
    Abstract: A method of testing using a memory test apparatus connected to a memory device includes receiving a test command. When the test command is a finite state machine (FSM) operation command, the memory device is tested in accordance with the FSM operation command, and an operation is performed to output a result depending on a pass/fail result. But, when the test command is a direct access command, an auto-operation test of input data is performed in a test region according to received address information, and a test result is output, which may include output data with fail information or the auto-operation.

  • Patent number: 11070380
    Abstract: An authentication apparatus, included in a device supporting a network communication, includes a certificate handler that receives a certificate of an opponent and parses or verifies the certificate of the opponent. Cryptographic primitives receive an authentication request of the opponent, generate a random number in response to the authentication request, generate a challenge corresponding to the random number, and verify a response of the opponent corresponding to the challenge. A shared memory stores the parsed certificate, the random number, the challenge, and the response. An authentication controller controls the certificate handler, the cryptographic primitives, and the shared memory through a register setting, according to an authentication protocol.
