Abstract: Methods, systems, and devices for flexible bus management are described. A memory device may transfer data between the memory device and another device (e.g., host device) using a bus including a plurality of data pins. The memory device may transfer data according to a first bus configuration (e.g., according to a first width corresponding to using all of the data pins). After receiving an indication to adjust the configuration, the memory device may adjust the first bus configuration to a second bus configuration where the bus operates according to a second width (e.g., using a subset of the data pins). The memory device may adjust the bus width between the other device and the memory device without adjusting an internal bus width of the memory device (e.g., internal busses that transfer data from the data pins to various components within the memory device).

Abstract: Methods, systems, and devices for life expectancy monitoring for memory devices are described. Some memory devices may degrade over time, and this degradation may include or refer to a reduction of an ability of the memory device to reliably store, read, process, or communicate information, among other degradation. In accordance with examples as disclosed herein, a system may include components configured for monitoring health or life expectancy of the memory device, such as components that perform comparisons between signals or other operating characteristics resulting from operating at the memory device and one or more threshold values that may be indicative of a life expectancy of the memory device. In various examples, a memory device may perform a subsequent operation based on such a comparison, or may provide an indication of a life expectancy to a host device based on one or more comparisons or determinations about health or life expectancy.

Abstract: Methods, systems, and devices for monitoring and adjusting access operations at a memory device are described to support integrating monitors or sensors for detecting memory device health issues, such as those resulting from device access or wear. The monitoring may include traffic monitoring of access operations performed at various components of the memory device, or may include sensors that may measure parameters of components of the memory device to detect wear. The traffic monitoring or the parameters measured by the sensors may be represented by a metric related to access operations for the memory device. The memory device may use the metric (e.g., along with a threshold) to determine whether to adjust a parameter associated with performing access operations received by the memory device, in order to implement a corrective action.

Abstract: Methods, systems, and devices for memory traffic monitoring are described. The monitoring may include traffic monitoring of access operations performed at various components of the memory device, or may include sensors that may measure parameters of components of the memory device to detect wear. The traffic monitoring or the parameters measured by the sensors may be represented by a characteristic related to an operational bias of circuits of the memory device. The memory device may use the characteristic (e.g., along with a threshold) to determine whether to adjust a parameter associated with performing access operations received by the memory device, in order to implement a corrective action.

Abstract: Methods, systems, and devices for refresh counters in a memory system are described. In some examples, a memory device may include two or more counters configured to increment a respective count based on refresh operations performed on a memory array. A comparison may be made between two or more of the respective counts, which may include determining a difference between the respective counts or a difference in rate of incrementing. A memory device may transmit an indication to a host device based on determining a difference between counters, and the memory device, the host device, or both, may perform various operations or enter various operational modes based on the determined difference.

Abstract: Apparatuses, systems, and methods related to memory pooling between selected memory resources are described. A system using a memory pool formed as such may enable performance of functions, including automated functions critical for prevention of damage to a product, personnel safety, and/or reliable operation, based on increased access to data that may improve performance of a mission profile. For instance, one apparatus described herein includes a memory resource, a processing resource coupled to the memory resource, and a transceiver resource coupled to the processing resource. The memory resource, the processing resource, and the transceiver resource are configured to enable formation of a memory pool between the memory resource and another memory resource at another apparatus responsive to a request to access the other memory resource transmitted from the processing resource via the transceiver.

Abstract: Apparatuses, systems, and methods related to sharing a memory resource among physically remote entities are described. A system sharing a memory resource among physically remote entities may enable performance of functions, including automated functions critical for prevention of damage to a product, personnel safety, and/or reliable operation, based on increased access to data that may improve performance of a mission profile. For instance, one apparatus described herein includes a first vehicle configured to determine an availability of processing resources or memory capacity, or both, at the first vehicle based at least in part on a current operating mode of the first vehicle, receive a request from a second vehicle to use at least a portion of the processing resources or the memory capacity, or both, to perform a processing operation at a second vehicle, wherein the request from the second vehicle is associated with insufficient processing capability or memory capacity, or both, at the second vehicle, and perform at least a portion of the processing operation or allow access to the available memory capacity, or both, at the first vehicle in response to the request and based at least in part on determining the availability of the processing resources or the memory capacity, or both.

Abstract: Methods, systems, and devices for memory device health evaluation at a host device are described. The health evaluation relates to a host device that is associated with a memory device that monitors and reports health information, such as one or more parameters associated with a status of the memory device. The memory device may transmit the health information to the host device, which may perform one or more operations and may transmit the health information to a device of another entity of a system (e.g., ecosystem) including the host device. The host device may include one or more circuits for transmitting and processing the health information, such as a system health engine, a safety engine, a communication component, or a combination thereof. Based on a determination by the host device or information received from an external device, the host device may transmit a command to the memory device.

Abstract: Methods, systems, and devices for inter-device communications for memory health monitoring are described. These communications relate to a host device that is associated with a memory device that monitors and reports health information (e.g., one or more parameters associated with a status of the memory device). The memory device may transmit the health information to the host device (e.g., a vehicle or a computer of the vehicle), which may perform one or more operations and transmit the health information to another entity of a system (e.g., ecosystem) including the host device. The host device may additionally or alternatively use the health information. In some cases, the other entity may receive the health information and transmit a signal back to the host device based on the health information. The other entity of the ecosystem may receive the health information and may make a determination based on the health information.
