Abstract: A system and method for preserving block experiencing wordline failure in memory devices. An example method includes performing, by a processor, a write operation to program data to a set of memory cells addressable by a first wordline of a plurality of wordlines of a block of a memory device; determining that a program fault occurred during the write operation; determining a number of wordlines referenced by a program fault data structure that are associated with the block; and responsive to determining that the number of wordlines fails to satisfy a threshold criterion, releasing a second wordline of the plurality of wordlines to be available for write operations.

Abstract: This disclosure is directed to techniques for recording and recognizing physiological parameter patterns associated with symptoms. A medical device system includes a medical device including one or more sensors configured to generate a signal that indicates a parameter of a patient. Additionally, the medical device system includes processing circuitry configured to receive data indicative of a user indication of an experienced symptom; determine a plurality of parameter values of the parameter based on a portion of the signal corresponding to a period of time including a time before the user indication and a period of time after the user indication. Additionally, the processing circuitry is configured to identify, based on a reference set of parameter values of the plurality of parameter values, the experienced symptom. Additionally, the processing circuitry is configured to save, to a database in memory, a set of data including the experienced symptom and patient parameters.
