Abstract(in English) | In this paper, we propose the mixed associativity scheme using 7T/14T SRAM, which can reduce the minimum operating voltage of the entire cache efficiently. The proposed mixed associativity scheme allows associativities in each index to be various. It exploits the characteristics of manufacturing-induced defects in memory structures and the recovery feature of 7T/14T SRAM. The proposed scheme has no additional cycle penalty. According to our measurement results, the proposed scheme can reduce the minimum operating voltage by 80mV. Area estimation results show that the area overhead of the proposed cache scheme is 5.22% in 64-KB cache 8-way set-associative cache. |
