Abstract
Description
Claims (3)
- 반도체 소자의 프리차지 전압 발생회로에 있어서, 하이 임피던스 특성을 갖고 항상 동작하여, 출력단이 일정 전위를 유지할 수 있도록 일정 전류를 구동하는 하이 임피던스 회로와, 동작 모드에서 대기 모드(standby mode)로 전환하는 초기에 일정시간 동안만 동작하여, 출력단이 일정 전위를 유지할 수 있도록 전류를 구동하는 로우 임피던스 회로를 포함하는 것을 특징으로 하는 프리차지 전압 발생회로.
- 제1항에 있어서, 동작 모드(active mode)시에만 동작하여 출력단이 일정 전위를 유지할 수 있도록 전류를 구동하는 두번째 로우 임피던스 회로를 추가로 포함하는 것을 특징으로 하는 프리차지 전압 발생회로.
- 제1항 또는 제2항에 있어서, 상기 로우 임피던스 회로를 반도체 소자의 전체 동작을 제어하는/ RAS(Row Address Strobe) 신호에 의해 출력된 신호로 제어하는 것을 특징으로 하는 프리차지 전압 발생 회로.
