  • Patent number: 11087816
    Abstract: A ferroelectric capacitor of a memory cell may be in electronic communication with a sense capacitor through a digit line. The digit line may be virtually grounded during memory cell sensing, limiting or avoiding voltage drop across the digit line, and allowing all or substantially all of the stored charge of the ferroelectric capacitor to be extracted and transferred to the sense capacitor. Virtually grounding the digit line may be achieved by activating a switching component (e.g., a p-type field-effect transistor) that is electronic communication with the digit line. The charge of the ferroelectric capacitor may be transferred through the switching component. A sense amplifier may compare the voltage of the sense capacitor to a reference voltage in order to determine the stored logic state of the memory cell.

  • Patent number: 11087819
    Abstract: Memory devices and methods of operating memory devices in which refresh management operations can be scheduled on an as-needed basis for those memory portions where activity (e.g., activations in excess of a predetermined threshold) warrants a refresh management operation are disclosed. In one embodiment, an apparatus comprises a memory including a memory location, and circuitry configured to determine a count corresponding to a number of activations at the memory location, to schedule a refresh management operation for the memory location in response to the count exceeding a first predetermined threshold, and to decrease the count by an amount corresponding to the first predetermined threshold in response to executing the scheduled refresh management operation. The circuitry may be further configured to disallow, in response to determining that the count has reached a maximum permitted value, further activations at the memory location until after the count has been decreased.

  • Patent number: 11087854
    Abstract: A high current fast read scheme can enable improved read disturb without negatively impacting read performance. In one example, a fast read scheme involves applying a higher current as soon as the cell thresholds. In one example, circuitry detects the threshold event and turns on a bypass control transistor to bypass the circuitry applying the read voltage to enable a higher voltage and therefore higher current as soon as possible. The read time can thus be decreased (or at least not increased) and read disturb improved.

  • Patent number: 11087858
    Abstract: A memory device comprises, on an integrated circuit or multi-chip module, a memory including a plurality of memory blocks, a controller, and a refresh mapping table in non-volatile memory accessible by the controller. The controller is coupled to the memory to execute commands with addresses to access addressed memory blocks in the plurality of memory blocks. The refresh mapping table has one or more entries, an entry in the refresh mapping table mapping of an address identifying an addressed memory block set for refresh to a backup block address. The controller is responsive to a refresh command sequence with a refresh block address to execute a refresh operation, and is configured to restore mapping of the refresh block address to the backup block address upon power-on of the device, to scan the refresh mapping table for a set entry, and to register the set entry in the refresh mapping table.

  • Patent number: 11087860
    Abstract: In pattern discovery visual analytics, a patient data table (14) is generated that tabulates, for each patient, attribute values for a set of attributes. A positive or negative prediction is generated for each patient for a target value of a target attribute using a prediction pattern (20) of attribute values for w attributes (22). The prediction is positive if at least a threshold fraction (26) of the w attributes of the patient match the prediction pattern, is negative otherwise. Patients are grouped into a selected proportion of a confusion matrix (30) in accord with the positive or negative predictions and actual values of the target attribute T in the patient data table. A display component (4) displays a representation (42) of patient statistics for the selected proportion of the confusion matrix on a per-attribute basis for attributes of the w attributes. A patient cohort (44) is identified using the representation.
