  • Patent number: 11775378
    Abstract: Methods, systems, and devices for memory health status reporting are described. A memory device may output to a host device a parameter value, which may be indicative of metric or condition related to the performance or reliability (e.g., a health status) of the memory device of the memory device. The host device may thereby determine that the memory device is degraded, possibly prior to device or system failure. Based on the parameter value, the host device may take preventative action, such as quarantining the memory device, deactivating the memory device, or swapping the memory device for another memory device.

  • Publication number: 20230197181
    Abstract: Methods, systems, and devices for link evaluation for a memory device are described. A memory device may receive signaling over a channel and may identify logic values encoded into the signaling based on sampling the signaling against a reference voltage. The sampling may occur at a reference time within a sampling period. To evaluate a quality (e.g., margin of error) of the channel, the memory device may adjust the reference voltage, the reference time, or both, and either the memory device or the host device may determine whether the memory device is still able to correctly identify logic values encoded into signaling over the channel. In some cases, the channel quality may be evaluated during a refresh cycle or at another opportunistic time for the memory device.

  • Publication number: 20210181990
    Abstract: Methods, systems, and devices for interrupt signaling for a memory device are described. A memory device may transmit an interrupt signal to a host device to alter a sequence of operations that would otherwise be executed by the host device. The memory device may transmit the interrupt signal in response to detecting an error condition at the memory device, a performance degradation at the memory device, or another trigger event. In some examples, the memory device may include a dedicated interrupt pin for transmitting interrupt signals. Alternatively, the memory device may transmit interrupt signals via a pin also sued to transmit error detection codes. For example, the memory device may transmit an interrupt signal before or after an error detection code or may invert the error detection code to indicate the interrupt, in which case the inverted error detection code may act as an interrupt signal.

  • Patent number: 8595449
    Abstract: An integrated circuit includes: a resistive memory having an array of resistive memory cells; a memory controller that controls operation of the resistive memory in accordance with external commands from an external device; and a memory scheduler coupled to the resistive memory and to the memory controller. The memory scheduler schedules internal maintenance operations within the resistive memory in response to trigger conditions indicated by at least one sensor signal or external command. The operation of the memory scheduler and performance of the internal maintenance operations are transparent to the external device and, optionally, transparent to the memory controller.
