  • Patent number: 11896681
    Abstract: The present invention provides hydrophilic bilirubin derivative particles containing a metal, a use thereof, and a preparation method therefor. The bilirubin derivative particles of the present invention form coordinate bonds with various metals, and thus can be used in MR diagnosis, CT diagnosis, photo-acoustic diagnosis, PET diagnosis, or optical diagnosis. The bilirubin derivative particles of the present invention can release an anticancer drug encapsulated therein to the outside by the combination with a platinum-based anticancer drug and the degradation by a stimulation of light/reactive oxygen species, and exhibit anti-inflammatory and anticancer activities, and thus the bilirubin derivative particles of the present invention have a concept of theranostics in which the bilirubin derivative particles can be for therapeutic uses as well as diagnostic uses.

  • Patent number: 11894099
    Abstract: Described apparatuses and methods enable communication between a host device and a memory device to establish relative delays between different data lines. If data signals propagate along a bus with the same timing, simultaneous switching output (SSO) and crosstalk can adversely impact channel timing budget parameters. An example system includes an interconnect having multiple data lines that couple the host device to the memory device. In example operations, the host device can transmit to the memory device a command indicative of a phase offset between two or more data lines of the multiple data lines. The memory device can implement the command by transmitting or receiving signals via the interconnect with different relative phase offsets between data lines. The host device (e.g., a memory controller) can determine appropriate offsets for a given apparatus. Lengths of the offsets can vary. Further, a system can activate the phase offsets based on frequency.

  • Publication number: 20230343381
    Abstract: Described apparatuses and methods relate to a bank-level self-refresh for a memory system. A memory device can include logic that implements self-refresh operations in the memory device. The logic may perform self-refresh operations on a set of banks of the memory device that is less than all banks within the memory device. The set of banks of the memory device may be determined such that the peak current in a power distribution network of the memory device is bounded when the self-refresh operation is performed. Accordingly, bank-level self-refresh can reduce a cost of the memory device of a memory system by enabling use of a less complicated power distribution network. The bank-level self-refresh may also be implemented with different types of refresh operations. Amongst other scenarios, bank-level self-refresh can be deployed in memory-expansion environments.
