Claims (4)
- 고전압에서 동작하는 칩과 저전압에서 동작하는 칩을 한 칩 즉 마스타 칩에서 동시에 사용하는 혼합된 입출력 셀의 레이아웃방법에 있어서; 상기 마스타 칩내에 다수개의 메모리 셀들로 구성된 중심영역에서 상기 고전압과 저전압에 의해 동작하는 각기 고전압영역과 저전압영역의 면적을 용도에 따라 적절하게 조절가능하고, 상기 고전압영역과 저전압영역의 전원을 분리하기 위한 웰영역을 각기 형성하고, 상기 메모리 셀들의 입출력 동작을 수행하기 위한 입출력영역을 대응되는 상기 고전압영역과 저전압영역의 외곽에 배치하고, 상기 고전압과 저전압의 논리레벨변환을 위한 논리레벨변환영역을 상기 고전압영역과 저전압영역 사이에 배치함을 특징으로 하는 혼합된 입출력 셀의 레이아웃방법.
- 제1항에 있어서, 상기 고전압은 5볼트이고, 상기 저전압은 3.3볼트임을 특징으로 하는 혼합된 입출력셀의 레이아웃방법.
- 제2항에 있어서, 상기 중심영역의 고전압영역과 저전압영역은 고속동작을 수행하기를 원할때는 상기 저전압영역보다 고전압영역에 더 많은 면적을 할당하고, 저전원소비를 원할 때는 상기 고전압영역보다 저전압영역에 더 많은 면적을 할당하는 것을 특징으로 하는 혼합된 입출력 셀의 레이아웃방법.
- 제1항에 있어서, 상기 중심영역의 고전압영역과 저전압영역은 절반으로 나뉘어짐을 특징으로 하는 혼합된 입출력 셀의 레이아웃방법.
