Event counters for memory operations

A system, comprising:

• a memory comprising an array of memory cells;
• and
• a counter coupled to the memory and comprising a number of sensing components and a compartor;
• wherein each respective sensing component comprises a first capacitor initially charged to a first voltage and is configured to receive a respective second voltage indicative of a respective event;
• wherein each respective first capacitor is configured to be coupled in parallel with a second capacitor of the counter in response to each respective sensing component receiving the respective first voltage so that each respective first capacitor discharges into the second capacitor until each respective first capacitor and the second capacitor reach a third voltage;
• and
• wherein the comparator is configured to compare the third voltage to a reference voltage to determine whether the number of sensing components receiving the respective second voltage is greater than or equal to a threshold quantity.

A computing system, comprising:

• a host;
• a memory system coupled to the host and comprising:
• a system controller;
• and
• a memory coupled to the system controller and comprising:
• an embedded controller;
• a memory array coupled to the embedded controller;
• and
• a counter comprising a number of sensing components, the counter configured to:
• receive a respective first voltage indicative of a respective switching event at each respective sensing component of the number of sensing components, each respective sensing component comprising a respective first capacitor initially charged to a second voltage;
• transfer a particular amount of charge from each respective first capacitor into an initially discharged second capacitor by discharging each respective first capacitor into the second capacitor in response to each respective sensing component receiving the respective first voltage so that the second capacitor is charged to a third voltage;
• and
• compare the third voltage to a reference voltage by a comparator to determine whether the number of sensing components receiving the respective first voltage is greater than or equal to a threshold quantity.
