1. 18 : 용량을 표시하는데 이 모델의 경우 16M byte를 나타냄.
※16Mbyte에는 3가지가 있습니다.
16 / 17 / 18 : 3가지가 있는데 Refresh와 컨트롤러에 따라 구분합니다.
2. 16 : I/O를 나타냄. BY 16 (16Bit)type임을 나타내는 것입니다.
3. 3 : 메모리 종류를 구분함.
※ 0 : Standard MEM. 3 : EDO MEM.
※ - 모듈(기판)에 10 이 적혀있는 모델도 EDO MEM임, 단품이 EDO이면
모듈도 EDO메모리임.
4. 6 : 메모리 속도를 나타냄.
※ 6 : 60 ns(나노초), 7 : 70 ns, 8 : 80 ns.
