  • Publication number: 20190235787
    Abstract: According to one embodiment, a memory system receives from a host a first write request including a first block identifier designating a first write destination block to which first write data is to be written. The memory system acquires the first write data from a write buffer temporarily holding write data corresponding to each of the write requests, and writes the first write data to a write destination page in the first write destination block. The memory system releases a region in the write buffer, storing data which is made readable from the first write destination block by writing the first write data to the write destination page. The data made readable is a data of a page in the first write destination block preceding the write destination page.

  • Patent number: 10365201
    Abstract: A CPU of an analysis apparatus performs a fluid analysis and derives transient distribution information that represents an accumulation distribution of a particulate layer on an inflow-side inner circumferential surface of a honeycomb structure at a time point after a short time interval ?t (step S130). The CPU then repeatedly performs a fluid analysis by taking into account the transient distribution information derived previous time to repeatedly derive transient distribution information (steps S130 to S150) and then derives post-transient-analysis distribution information that represents the accumulation distribution of the particulate layer at a later time point (step S160).
