Abstract: A garbage collection apparatus and a method using the same are disclosed. The garbage collection method comprises: making a list of objects that must be deleted from a memory; calculating a predetermined residual time for responding to an external command; deleting the listed objects from the memory during the residual time; and storing a list of remaining objects that have not been deleted from the memory during the residual time. Accordingly, communication failure due to a response delay or timeout is prevented by distributed processing loads of garbage collection.

Abstract: Provided is a method of storing data in a non-volatile memory, including generating and storing logs including data to be stored and an address of the non-volatile memory in response to a data-writing request, and comparing addresses of the logs and storing data corresponding to the same page by the unit of page in a corresponding area of the non-volatile memory. The method makes it possible to minimize delay in storing data, reduce the number of accesses to the non-volatile memory and uniformly write data in the whole non-volatile memory, thereby minimizing a response time of the non-volatile memory and increasing the lifetime of the non-volatile memory.
