  • Patent number: 10936418
    Abstract: Uncorrectable memory errors may be reduced by determining a logical array address for a set of memory arrays and transforming the logical array address to at least two unique array addresses based, at least in part, on logical locations of at least two memory arrays within the set of memory arrays. The at least two memory arrays are then accessed using the at least two unique array addresses, respectively.

  • Patent number: 10678315
    Abstract: Data reliability and integrity may be compromised when memory resources used to store the data reach elevated temperatures. A sensor in the memory resource may monitor the temperature of the memory resource in real-time. A comparator in the memory resource may indicate a high temperature condition to a memory controller. The memory controller, in response to the high temperature condition, can restrict or halt data flow to the memory resource. When the real-time temperature of the memory resource falls below a defined threshold, the memory controller may resume data flow to the memory resource.

  • Patent number: 10325652
    Abstract: Technology for verifying cell programming for a phase change memory array is disclosed. In an example, a method may include sending a reset pulse to a phase change memory cell. The method may further include sensing a threshold voltage of the phase change memory cell in response to applying first and second verify voltages across the phase change memory cell, where the second verify voltage is lower than the first verify voltage. The method may also include determining whether the threshold voltage of the phase change memory cell was below the first or second verify voltages.

  • Patent number: 10289597
    Abstract: Several systems and methods of chip select are described. In one such method, a device maintains two identifiers, (ID_a and ID_m). When the device receives a command, it examines the values of ID_a and ID_m relative to a third reference identifier (ID_s). If either ID_a or ID_m is equivalent to ID_s, the device executes the command, otherwise, the device ignores the command. By using two different identification methods, a system has options in choosing to activate devices, being able to selectively switch between selecting multiple devices and single devices in a quick manner. In another such method, a device may have a persistent area that stores identification information such as an ID_a. Thus, system functionality may remain independent from any defect/marginality associated with the physical or logical components required for initial ID_a assignment of all devices in the system.

  • Patent number: 10062444
    Abstract: An integrated circuit, that may be a part of an electronic system, may include a first set of storage cells to store settings and a second set of storage cells to store alternate settings. At least one control cell may also be included in the integrated circuit. The at least one control cell may indicate whether to use the settings stored in the first set of storage cells, or the alternate settings stored in the second set of storage cells, to control one or more operating parameters of the integrated circuit. Methods for using the alternate setting are also described.

  • Patent number: 10056139
    Abstract: Apparatus, systems, and methods to correct for threshold voltage drift in non-volatile memory devices are disclosed and described. In one example, a compensated demarcation voltage is generated by either a time-based drift compensation scheme or a disturb-based drift compensation scheme, and read and write operations to the non-volatile memory are carried out using the compensated voltage threshold.
