As capacity and complexity of on-chip cache memory hierarchy increases, theservice cost to the critical loads from Last Level Cache (LLC), which arefrequently repeated, has become a major concern. The processor may stall for aconsiderable interval while waiting to access the data stored in the cacheblocks in LLC, if there are no independent instructions to execute. To provideaccelerated service to the critical loads requests from LLC, this workconcentrates on leveraging the additional capacity offered by replacingSRAM-based L2 with Spin-Transfer Torque Random Access Memory (STT-RAM) toaccommodate frequently accessed cache blocks in exclusive read mode in favor ofreducing the overall read service time. Our proposed technique partitions L2cache into two STT-RAM arrangements with different write performance and dataretention time. The retention-relaxed STT-RAM arrays are utilized toeffectively deal with the regular L2 cache requests while the high retentionSTT-RAM arrays in L2 are selected for maintaining repeatedly read accessedcache blocks from LLC by incurring negligible energy consumption for dataretention. Our experimental results show that the proposed technique can reducethe mean L2 read miss ratio by 51.4% and increase the IPC by 11.7% on averageacross PARSEC benchmark suite while significantly decreasing the total L2energy consumption compared to conventional SRAM-based L2 design.
