  • Patent number: 12165725
    Abstract: According to one embodiment, a memory system includes a non-volatile first memory with first storage areas. A controller executes a first read operation on a second storage area of the first storage areas. When an error correction in the first read operation fails, the controller acquires a first measured value being a value of a read voltage for suppressing the number of occurrences of error bits in the second storage area. The controller updates, on the basis of the first measured value, one of first candidate values of the read voltage with a second candidate value. When the error correction in a second read operation for a third storage area of the first storage areas fails, the controller executes the read operation once or more on the third storage area by using, as the read voltages, different first candidate values of the first candidate values.

    Abstract: Provided is a system for accurately calculating the degree of clogging of a filter with reduced amount of required data. The system includes a controller. The controller stores a judgment permission condition including that the flow rate of hydraulic fluid passing through a filter exceeds a predetermined flow rate threshold, and calculates: a judgment-permissible time, which is an integrated value of time in which the judgment permission condition is satisfied; and a judgment target time, which is an integrated value of time in which the judgment permission condition is satisfied and the differential pressure across the filter exceeds a predetermined differential pressure threshold. The controller calculates the degree of clogging of the filter on the basis of a comparison between the judgment permission time and the judgment target time.
