Claim Text:
1. A method of profiling a number of times that an input/output address of a semiconductor device is accessed, the method comprising: producing at least one hash value by performing a hash operation on the accessed input/output address; and profiling the number of times that the input/output address of the semiconductor device is accessed, based on the at least one hash value, wherein the profiling of the number of times comprises: determining whether the input/output address is stored in a storage unit, based on the at least one hash value, increasing a number of access times stored in the storage unit corresponding to the input/output address when it is determined that the input/output address is stored in the storage unit, and reducing a number of times that the input/output address stored in the storage unit corresponding to the at least one hash value has been accessed when it is determined that the input/output address is not stored in the storage unit.
