Reducing memory reference energy with opportunistic virtual caching
Most modern cores perform a highly-associative translation look aside buffer (TLB) lookup on every memory access. These designs often hide the TLB lookup latency by overlapping it...

A case for exploiting subarray-level parallelism (SALP) in DRAM
Modern DRAMs have multiple banks to serve multiple memory requests in parallel. However, when two requests go to the same bank, they have to be served serially, exacerbating the h...
