A prefetching system receives a memory read request having an associated address. In response to a determination that a most significant portion of the associated address is not present within slots of an array for storing the most significant portion of predicted addresses, a prefetch FIFO (First In-First Out) counter is modified to point to a next slot of the array and a new predicted address is generated in response to the received most significant portion of the associated address and is placed in the next slot of the array. The prefetch FIFO counter cycles through the slots of the array before wrapping around to a first slot of the array for storing the most significant portion of predicted addresses.
