This paper contains corrections to published results on the RAMpage memory hierarchy. The originally published results contained erroneous values for cache miss penalties for a conventional cache architecture against which the RAMpage hierarchy was being compared. The incorrect results showed that RAMpage with context switches on misses to DRAM had similar performance to a conventional 2-way associative L2 cache-based hierarchy. The corrected results show that the RAMpage hierarchy in fact outperforms a conventional 2-way associative cache hierarchy by up to 29%, for the measured variations.
