  • Publication number: 20220300370
    Abstract: Described apparatuses and methods provide configurable error correction code (ECC) circuitry and schemes that can utilize a shared ECC engine between multiple memory banks of a memory, including a low-power double data rate (LPDDR) memory. A memory device may include one or more dies with multiple memory banks. The configurable ECC circuitry can use an ECC engine that services a memory bank by producing ECC values based on data stored in the memory bank when data-masking functionality is enabled. When data-masking functionality is disabled, the configurable ECC circuitry can use the shared ECC engine that services at least two memory banks by producing ECC values with a larger quantity of bits based on respective data stored in the at least two memory banks. By using the shared ECC engine responsive to the data-masking functionality being disabled, the ECC functionality can provide higher data reliability with lower die area utilization.

  • Patent number: 11421017
    Abstract: The present invention relates to a recombinant herpes simplex virus (HSV) containing an expression cassette capable of expressing a fused protein of a cancer-cell-targeting domain and an extracellular domain of HVEM and the use thereof. When the recombinant HSV infects and enters target cells, which are cancer cells, HSV proliferates, and an adapter, which is the fused protein, is expressed in the cells and is released to the outside of the cells along with the proliferated HSV virion upon cell lysis, or is released even before the virion is released due to cell lysis when the adapter contains a leader sequence, and the fused protein released to the outside of the cells acts to induce the HSV virion to infect surrounding cancer cells expressing a target molecule recognized by the cancer-cell-targeting domain or to increase the infection efficiency thereof.

  • Publication number: 20220206717
    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: 20220209998
    Abstract: Described apparatuses and methods are directed to equalization with pulse-amplitude modulation (PAM) signaling. As bus frequencies have increased, the time for correctly transitioning between voltage levels has decreased, which can lead to errors. Symbol decoding reliability can be improved with equalization, like with decision-feedback equalization (DFE). DFE, however, can be expensive for chip area and power usage. Therefore, instead of applying DFE to all voltage level determination paths in a receiver, DFE can be applied to a subset of such determination paths. With PAM4 signaling, for example, a DFE circuit can be coupled between an output and an input of a middle slicer. In some cases, symbol detection reliability can be maintained even with fewer DFE circuits by compressing a middle eye of the PAM4 signal. The other two eyes thus have additional headroom for expansion. Encoding schemes, impedance terminations, or reference voltage levels can be tailored accordingly.
