Description
Claims (4)
- 행선(11~1n)과, 이 행선에 의해 선택적으로 구동되는 메모리셀(311~3nm), 이 메모리셀에 접속되는 열선(21~2m), 이 열선에 접속되는 부하트랜지스터(16), 이 부하트랜지스터와 상기 열선의 사이에 소오스/드레인전류로가 접속되어 상기 열선의 전위에 따라 게이트전위가 제어되는 제 1 트랜지스터(15, 15A), 상기 열선에 접속되어 상기 열선의 전위가 소정의 전위 이상일 때 상기 열선의 전위를 상기 소정의 전위까지 방전시키는 방전수단(21~26,Ⅰ)을 구비한 것을 특징으로 하는 반도체기억장치.
- 제 1 항에 있어서, 상기 소정의 전위는 상기 제 1 트랜지스터의 게이트전위 보다도 그 제 1 트랜지스터의 문턱치 전압분 만큼 낮은 값인 것을 특징으로 하는 반도체기억장치.
- 제 1 항에 있어서, 상기 방전수단은 상기 열선에 드레인과 게이트가 접속된 문턱치 전압이 대략 0V인 제 2 트랜지스터(23)를 구비하고, 그 제 2 트랜지스터의 소오스를 전원단자와 접지사이에 직렬로 접속된 제 3 트랜지스터(21) 및 제 4 트랜지스터(24)의 접속중점에 접속시키며 상기 제 3 트랜지스터(21)의 게이트를 상기 제 1 트랜지스터(15)의 게이트에 접속시킨 구성으로 되어 있고, 더욱이 상기 제 1 트랜지스터의 문턱치 전압과 제 3 트랜지스터의 문턱치 전압이 거의 동일한 것을 특징으로 하는 반도체기억장치.
- 제 1 항에 있어서, 상기 제 1 트랜지스터는 몬턱치 전압이 대략 0V인 트랜지스터이고, 상기 방전수단은 상기 열선과 상기 제 1 트랜지스터의 게이트 사이에 접속된 몬턱치 전압이 대략 0V인 제 5 트랜지스터(26)를 구비하여 그 제 5 트랜지스터(26)의 게이트를 상기 열선에 접속시킨 것임을 특징으로 하는 반도체기억장치.
