A network device may include an off-chip memory to store a free-list of buffer pointers. The network device may further include an on-chip controller that includes a prefetch buffer. The prefetch buffer may store unallocated buffer pointers that point to available memory locations in a different off-chip memory. The on-chip controller may receive an unallocated buffer pointer, determine, in response to receiving the unallocated buffer pointer, whether the prefetch buffer is full, store the unallocated buffer pointer in the prefetch buffer when the prefetch buffer is determined not to be full, and store the unallocated buffer pointer in the free-list, in the off-chip memory, when the prefetch buffer is determined to be full.
