Abstract: A memory system and method for performing adaptive prefetch in a memory system are provided. The method includes receiving a first data request including a first address of a first data page stored in a memory device; and performing a lookup operation using an adaptive prefetch table, to determine whether a prefetch operation should be performed based on the received first data request. The adaptive prefetch table includes an entry for the first data page corresponding to the received first data request, and the entry for the first data page includes an address of a predicted next page, and a weight factor of the predicted next page.

Abstract: A method and apparatus are provided for performing early prefetch in a memory system. A method includes receiving a data request including an address of a data page stored in a memory device; storing the data request at a first position in a request queue; accessing the data request stored at the first position and performing a first lookup operation for the data request; updating the device request queue, which includes moving the data request stored at the first position to a second position in the request queue; and accessing the data request stored at the second position and performing a second lookup operation for the data request.
