  • Publication number: 20190243577
    Abstract: A data structure is maintained for performing a program operation that is allowed to be suspended to perform reads in a NAND device, where the data structure indicates a plurality of tiers, where each tier of the plurality of tiers has a number of allowed suspends of the program operation while executing in the tier, and where a sum of the number of allowed suspends for all tiers of the plurality of tiers equals a maximum allowed number of suspends of the program operation. In response to performing a resume of the program operation, after performing a read following a suspend of the program operation, a determination is made of a tier of the plurality of tiers for the program operation and a subsequent suspend of the program operation is performed only after a measure of progress of the program operation has been exceeded in the determined tier.

  • Patent number: 10372846
    Abstract: A method for modeling air pollution includes receiving a weather model for a particular geographic region. Satellite-observed pollution observation data over the geographic region is received. A physical dispersion model for pollution over the geographic region is generated using the received weather model. The received satellite-observed pollution observation data is interpolated to the generated physical model. The interpolated satellite-observed pollution observation data and the generated physical model are combined using weighted coefficients for both the interpolated satellite-observed pollution observation data and the generated physical model. The weighted coefficients are calculated in accordance with a relative error in both the physical dispersion model and the satellite-observed pollution observation data.

  • Publication number: 20190227751
    Abstract: A memory device is designed to store data in multilevel storage cells (MLC storage cells). The memory device includes a controller that dynamically writes data to the storage cells according to a first MLC density or a second MLC density. The second density is less dense than the first density. For example, the controller can determine to use the first density when there is sufficient write bandwidth to program the storage cells at the first density. When the write throughput increases, the controller can program the same MLC storage cells at the second density instead of the first density, using the same program process and voltage.

    Abstract: Independent multi-plane commands for non-volatile memory devices are described. In one example, a three-dimensional (3D) NAND memory device includes 3D NAND dies, each die including multiple planes of memory cells. The device includes input/output (I/O) circuitry to receive multiple commands from a host, each of the received commands to access one of the planes. The device includes logic (which can be implemented with, for example, an ASIC controller, firmware, or both) to queue the commands in separate queues for each of the planes based on a target plane of each of the commands. The logic issues the commands to their target planes independent of other planes' status, and tracks completion status of the commands independently for each plane.
