    Abstract: Systems, methods, and apparatus related to selecting memory cells in a memory array of a memory device. In one approach, bias circuitry generates a voltage on an access line used to select a memory cell for programming. During programming, a controller connects a boost capacitor to the access line by controlling a switch. Connecting the boost capacitor causes an increase in the rate of discharge of the access line (e.g., discharge of a word line to a negative voltage). After programming, the controller disconnects the boost capacitor from the access line, and the boost capacitor is pre-charged in preparation for a next programming operation (e.g., on the same or a different memory cell).

    Abstract: A memory device having memory cells, voltage drivers, and a controller configured to determine, based on an attribute of a memory cell, whether to apply a drift cancellation pulse that is in the opposite polarity of a programming pulse configured to place the memory cell in a state to represent a bit of data. If the drift in the state of the memory cell from a previous programming operation to write data into the memory cell is predicted to be insufficient to prevent the selection of the memory cell during the application of the programming pulse, the drift cancellation pulse is skipped. Otherwise, the drift cancellation pulse is applied in the opposite polarity of the programming pulse.

    Abstract: Methods, systems, and devices for discharge current mitigation in a memory array are described. Access lines of a memory array may be divided into discrete segments, with each segment coupled with a driver for the access line by one or more vias respective to the segment. For example, a first segment of an access line may be coupled with a first set of memory cells, a second segment of the access line may be coupled with a second set of memory cells, and a driver may be coupled to the first segment by a first via and to the second segment by a second via. To access a memory cell in either the first set or the second, both the first segment of the access line and the second segment of the access line may be activated together by the common driver.

    Abstract: An integrated circuit memory device having: a memory cell; a current sensor connected to the memory cell; a voltage driver connected to the memory cell; and a bleed circuit connected to the voltage driver. During an operation to read the memory cell, the voltage driver drives a voltage applied on the memory cell. The bleed circuit is activated to reduce the voltage during a time period in which the current sensor operates to determine whether or not at least a predetermined level of current is presented in the memory cell.

    Abstract: Voltage balancing for a memory cell array is provided. One example method of voltage balancing for a memory array can include activating an access node coupled to a row of a memory array to provide voltage to the row of the memory array, activating a stabilizing transistor coupled to the row of the memory array to create a feedback loop, and activating a driving node coupled to a column of the memory array, wherein activating the driving node deactivates the stabilizing transistor once the column reaches a particular voltage potential.

    Abstract: Systems, apparatuses, and methods related to medical device data analysis are described. In some examples, a medical device is implanted in a user of the medical device and the data generated by the medical device is not easily accessible to the user. In an example, a controller can be configured to receive, by a mobile device coupled to a medical device, data from the medical device, where the data is a part of a baseline dataset related to the medical device. The controller can be configured to receive different data from the medical device, where the different data is received from the medical device as the different data is generated by the medical device, analyze the data from the medical device and the different data generated by the medical device, and perform an action based on the analyzed data and the different data generated by the medical device.
