  • Publication number: 20240136602
    Abstract: A consumer electronic device includes a battery module and a system chip. The battery module includes: battery cells, a heater adjacent to the battery cells, a battery management circuit coupled to the battery cells and the heater, and an electrical connector including an information transmission interface and a power transmission interface. The information transmission interface is coupled to the battery management circuit, and the power transmission interface is coupled to the battery cells. The system chip is coupled to the information transmission interface, and is configured to receive battery information from the battery management circuit through the information transmission interface. When a battery temperature of the battery information is lower than a first threshold, the system chip sends an activation signal to the battery management circuit through the information transmission interface, for the battery management circuit to activate the heater according to the activation signal.

  • Patent number: 11960769
    Abstract: A memory device includes a command decoder that implements security logic to detect a command sequence to read a security region of a memory array with continuous encrypted data and to output/input specific contexts for the data. Output/input of specific contexts can be during a dummy cycle to achieve greater performance. A host interfacing can, for example, execute a single command to both get the encrypted data and specific contexts that were used to encrypt the data. Our technology can implement transferring data on the system bus in ciphertext and encrypted by a different Nonce or a different session key than used in a previous transfer operation. In this way, data will be represented with different ciphertext on the bus at different sessions; thereby defending against a replay attack.

  • Patent number: 11922887
    Abstract: A display may include an array of pixels. Each pixel in the array includes an organic light-emitting diode coupled to associated thin-film transistors. The diode may be coupled to drive transistor circuitry, a data loading transistor, and emission transistors. The drive transistor circuitry may include at least two transistor portions connected in series. The data loading transistor has a drain region connected to a data line and a source region connected directly to the drive transistor circuitry. The data line may be connected to and overlap the drain region of the data loading transistor. The data line and the source region of the data loading transistor are non-overlapping to reduce row-to-row crosstalk.
