멀티미디어를 비롯한 많은 스트리밍 어플리케이션은 에너지 소비의 상당한 부분을 데이터 접근 연산 실행 명령어에 의해서 소비된다. 이러한 어플리케이션에서는 데이터 재사용성을 이용하여 에너지 소모량을 절감할 수 있다. 빈번히 사용되는 데이터를 고속의 상위 계층 메모리에 상주시켜 메인메모리 접근 횟수를 줄인다. 결과적으로 메모리 서브시스템에서 에너지 소모를 절감할 수 있게 된다. 본 연구에서는 어플리케이션의 재사용성을 분석하여 해당 어플리케이션에 특화된 스크래치패드 메모리 서브시스템 구성을 탐색하는 기법을 제안하고자 한다. 제안된 기법을 사용하면 하드웨어 제어 캐시 메모리와 비교하여 약 49% 에너지 소모를 절감하는 것이 가능하다.
