Memory hierarchy structure

메모리 계층 구조

빠른 순서대로, (레캐주보)

  1. 레지스터

    1. CPU내부에 위치한 고속 메모리

  2. 캐시 메모리

    1. L1, L2, L3 저장 장치가 있고, 자주 사용되는 데이터/ 명령어가 저장됨

  3. 주메모리

    1. RAM(Random Access Memory) - 휘발성 메모리이며, 프로그램 실행에 필요한 데이터를 저장합니다.

    2. ROM(Read-Only Memory) - 읽기 전용 메모리이자 비휘발성 메모리이며, 주로 컴퓨터 시스템의 기본 부트로더(시동 프로그램)나 펌웨어 등을 저장하는 데 사용됩니다. (예: 컴퓨터의 BIOS(기본 입출력 시스템))

  4. 보조 저장장치 (HDD, SSD)

    1. 대용량 데이터 및 파일 영구 저장을 위한 저장소.
