Patent number: 11966634Abstract: A memory system includes a memory device including memory chips and a controller. The controller includes first processors configured to perform first processing of network packets in at least one of a network layer and a transport layer of a network protocol, and second processors configured to perform second processing with respect to the memory chips. The controller is configured to extract tag information from a header of a network packet, select one of the first processors associated with a first memory chip that is identified based on the tag information, and control the selected one of the first processors to perform the first processing with respect to the network packet, which causes one of the second processors associated with the first memory chip to perform the second processing based on a payload of the network packet.Type: GrantFiled: July 21, 2022Date of Patent: April 23, 2024Assignee: Kioxia CorporationInventors: Tomoya Horiguchi, Daisuke Taki, Yukimasa Miyamoto, Takeshi Kumagaya

Publication number: 20240103080Abstract: A malfunction detection method detects a malfunction in an electronic control device. The electronic control device includes a normal power supply terminal connected to a normal power supply mounted on a vehicle, a starting power supply terminal connected to a starting power supply, a controller activated by supply of a normal voltage, and a wake-up circuit having a wake-up switch to open and close a power supply path from the normal power supply terminal to the controller. The wake-up circuit turns on the wake-up switch when a starting voltage input to the starting power supply terminal is equal to or greater than an ON threshold. The malfunction detection method includes determining by the controller that the wake-up switch has an ON sticking malfunction when the normal voltage is equal to or greater than a threshold and the starting voltage is less than the ON threshold.Type: ApplicationFiled: November 29, 2023Publication date: March 28, 2024Inventors: Tsuyoshi Tashima, Daisuke Kobayashi, Masaya Taki, Ryo Kano, Hisashi Kameya
