Real time trigger rate monitoring in a memory sub-system

Abstract:

The rate at which reads on a target memory portion initiate error recovery procedures can be monitored in real-time. Trigger rates can be used to perform analysis of a memory sub-system or to implement improvements in the memory sub-system. Trigger rate monitoring can include accessing a count of error recovery initializations for a target memory portion, wherein the count of error recovery initializations corresponds to a number of times a first stage of a multi-stage error recovery process was performed. Trigger rate monitoring can further include accessing a count of read operations corresponding to the target memory portion. The count of error recovery initializations and the count of read operations can be used to compute a trigger rate. The trigger rate, or multiple trigger rates from various times or from various target memory portions, can be used to compute a metric for the memory portion(s).
