WebReduced memory access latency: Interleaving allows the processor to access the memory in a more efficient manner, thereby reducing the memory access latency. This results in … WebIn low–order interleaving, consecutive addresses in the memory will be found in different memory banks. Consider a 64–word memory that is 4–way interleaved. This means that there are four memory banks, each holding 16 words. If this memory is also low–order interleaved, we have the following allocation of words to banks.
