Abstract: A scheduler, a method of operating the scheduler, and an electronic device including the scheduler are disclosed. The method of operating the scheduler configured to determine a model to be executed in an accelerator includes receiving one or more requests for execution of a plurality of models to be independently executed in the accelerator, and performing layer-wise scheduling on the models based on an idle time occurring when a candidate layer which is a target for the scheduling in each of the models is executed in the accelerator.

Abstract: A hammer refresh row address detector includes a control logic unit that receives a row address applied along with an active command, to increase a hit count stored in a corresponding entry when the row address is present in candidate aggressor row addresses stored in n entries. The control logic determines a candidate aggressor row address stored in an entry in which the hit count equals a threshold value to be a target aggressor row address. The control logic generates a victim row address adjacent to the target aggressor row address as a hammer refresh row address to accompany a hammer refresh command. The control logic increases the miss count value when the row address is not present in the candidate aggressor row addresses stored in the n entries and no hit count within the n entries is identical to the miss count value.
