Abstract: Methods, apparatuses, and systems related to an apparatus are described. The apparatus may include (1) a fuse array configured to provide non-volatile storage of fuse data and (2) local latches configured to store the fuse data during runtime of the apparatus. The apparatus may further include an error processing circuit configured to determine error detection-correction data for the fuse data. The apparatus may subsequently broadcast data stored in the local latches to the error processing circuit to determine, using the error detection-correction data, whether the locally latched data has been corrupted. The error processing circuit may generate corrected data to replace the locally latched data based on determining corruption in the locally latched data.

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: The present disclosure provides bit cells with data redundancy according to various aspects. In certain aspects, a bit cell includes a first memory element coupled to a write bit line, and a first write-access switch coupled between the first memory element and a ground. The bit cell also includes a second memory element coupled to the write bit line, and a second write-access switch coupled between the second memory element and the ground. The bit cell further includes a read-access switch coupled between the first memory element and a read bit line, wherein a control input of the read-access switch is coupled to a read-select line.

Abstract: Methods, systems, and devices for monitoring and reporting a status of a memory device are described. A memory device may include monitoring circuitry that may be configured to monitor health and wear information for the memory device. A host device may write to a dedicated register of the memory device, to configure the memory device with health status information reporting parameters. The memory device may monitor and report the health status information of the memory device based on the received reporting configuration or based on a default configuration, and may write one or more values indicative of the health status information to a dedicated register. The host device may perform a read on the readout register to obtain the health status information, as indicated by the one or more values, and may adjust operating procedures or take other actions based on the received health status information.
