    Abstract: A method of operating a memory device is provided, comprising determining a number of operations corresponding to a memory location during a first timing period; and scheduling an extra refresh operation for the memory location after the first timing period when the determined number of operations exceeds a predetermined threshold. A memory device is provided, comprising a memory including a memory location; and circuitry configured to: determine a number of operations corresponding to the memory location during a first timing period; and schedule an extra refresh operation for the memory location after the first timing period when the determined number of operations exceeds a predetermined threshold.

    Abstract: The present disclosure includes apparatuses and methods related to performing background operations in memory. A memory device can be configured to perform background operations while another memory device in a memory system and/or on a common memory module is busy performing commands received from a host coupled to the memory system and/or common memory module. An example apparatus can include a first memory device, wherein the first memory device can include an array of memory cells and a controller configured to perform a background operation on the first memory device in response to detecting a command from a host to a second memory device.

    Abstract: Methods of forming a transistor might include removing portions of a semiconductor to define a semiconductor fin having an upper portion having an uppermost surface at a first level and extending from the first level to a second level, and a lower portion, wider than the upper portion, having an uppermost surface at the second level and extending from the second level to a third level; forming first and second isolation regions at the third level and adjacent the lower portion of the semiconductor fin; forming a first dielectric overlying portions of the semiconductor that are lower than a level between the first level and the second level; forming a second dielectric overlying an exposed portion of the upper portion of the semiconductor fin; forming a conductor overlying the second dielectric; and forming first and second source/drains in the lower portion of the semiconductor fin at the second level.

    Abstract: Counters may be provided for individual word lines of a memory for tracking word line accesses. In some examples, multiple counters may be provided for individual word lines. In some examples, the counters may be included on the word lines. The counters may be incremented responsive to word line accesses in some examples. In some examples, the counters may be incremented responsive for a time period for which a word line is held open. In some examples, the counters may be incremented responsive to both word line accesses and time periods for which the word line is held open. In some examples, count values for the counters may be written back to the counters after incrementing. In some examples, the count values may be written back prior to receiving a precharge command.

    Abstract: Methods and apparatuses for a mobile device (e.g., a mobile phone) supporting virtual peripherals are described. The mobile device may include a projecting component configured to project images to external surfaces outside of the mobile device. In some cases, the mobile device may project an image of a document on a first external surface and an image of a keyboard on a second external surface. Moreover, the mobile device may include an imaging component to receive inputs based on sensing an input device overlaid on the projected image (e.g., the keyboard). Accordingly, the mobile device may function as a computer with an external monitor and a keyboard, virtually added to the mobile device. In some cases, the mobile device may serve two or more users or purposes at a time. For example, the mobile device may operate as an infotainment device of a vehicle.

    Abstract: Methods, systems, and devices related to host identification for a memory system are described. A memory system may receive an index value from a host system that is associated with an identification of the host system. The memory system may identify one or more operating parameter associated with the index value based on receiving the index value. The memory system controller may configure the memory system to utilize one or more operating parameters associated with the index value based on identifying the operating parameters. The memory system may output an indication to the host system that the operating parameters associated with the index value are configured to be utilized by the memory system.

    Abstract: A microelectronic device comprises a memory array region, a control logic region, and an additional control logic region. The memory array region comprises a stack structure comprising vertically alternating conductive structures and insulating structures, and vertically extending strings of memory cells within the stack structure. The control logic region underlies the stack structure and comprises control logic devices configured to effectuate a portion of control operations for the vertically extending strings of memory cells. The additional control logic region overlies the stack structure and comprises additional control logic devices configured to effectuate an additional portion of the control operations for the vertically extending strings of memory cells. Methods of forming a microelectronic device, and additional microelectronic devices and electronic systems are also described.
