Abstract: Methods and instruction sets are provided for performing event management in an embedded system such as a memory system including a memory device and a controller. The controller divides a group of objects, among a plurality of groups of objects, into a plurality of subgroups, each subgroup including a plurality of objects. The controller counts a number of times that each of the objects is affected by external event using an event counter, updates a count value of each of the subcounters each time an object in the corresponding subgroup is affected by the external event, updates a count value of a main counter each time one of the subcounters reaches a count value equal to a first threshold value; and performing system action on the group of objects, when the count value of the main counter is equal to a second threshold value.
