Before revision:  (2) there is no single memory type that can cater to all of the SoC accelerators (e.g., GDDR5 significantly outperforms other memories for multimedia  , while HMC significantly outperforms other memories for networking );
After revision:  (2) there is no single memory type that can cater to all components of a heterogeneous system (e.g., GDDR5 significantly outperforms other memories for multimedia , while HMC significantly outperforms other memories for networking );
