Unformatted text preview: ution as insignificant for this problem. Total energy is 8 GB / 64 * 2.56 uJ = 343.60 J to save DRAM and the same amount of energy is needed to restore DRAM after hibernation. The idle DRAM uses 1.6 W of power. The idle DRAM energy is 1.6 W multiplied by the time that it is idle: E = 1.6 * T. Simply solve for T when E is set to 343.6 * 2. 343.6 * 2 / 1.6 = T = 429.5 seconds or 7.16 minutes....
