Reporting Multiple Events associated with Mitigating Usage-Based Disturbance

A memory device comprising:

• a first circuit configured to:
• detect, during a first time interval, an occurrence of a first event associated with mitigating usage-based disturbance, the first event associated with a first event category, the first event category associated with a first risk level;
• detect, during a second time interval, an occurrence of a second event associated with mitigating usage-based disturbance, the second event associated with a second event category that differs from the first event category, the second event category associated with a second risk level that is higher than the first risk level;
• and
• generate an event signal that selectively indicates the occurrence of the first event and the occurrence of the second event;
• and
• a second circuit coupled to the first circuit, the second circuit configured to:
• generate, based on the event signal, a report signal having a characteristic that changes to selectively indicate the occurrence of the first event and the occurrence of the second event;
• and
• provide the report signal at an interface that is coupled to a memory controller, the report signal notifying the memory controller of the occurrence of the first event without interrupting the memory controller and the report signal alerting the memory controller to the occurrence of the second event in a manner that interrupts the memory controller.

A method performed by a memory controller, the method comprising:

• sending normal traffic to a memory device;
• receiving, from the memory device, a first report that indicates an occurrence of a first event associated with mitigating usage-based disturbance, the first event corresponding to a first event category, the first event category associated with a first risk level, the receiving of the first report occurring without interrupting the sending of the normal traffic;
• selectively performing, based on the first report, a first action that is associated with the first event category;
• receiving, from the memory device, a second report that indicates an occurrence of a second event associated with mitigating usage-based disturbance, the second event corresponding to a second event category that differs from the first event category, the second event category associated with a second risk level that is higher than the first risk level;
• and
• performing, based on the second report, a second action that is associated with the second event category, the second action interrupting the sending of the normal traffic to the memory device.
