Answer:
40% of instructions utilizes the data memory.
Explanation:
The MEM stage is where data is written and/or read from memory.
The LW instruction loads data from the data memory through a specified address and the SW instruction stores data to a specified address on the data memory. The LW instruction is 25% and the SW instruction is 15% which sums it up to a total of 40% instructions using the data memory.
