Abstract
Description
Claims (4)
- 매트릭스 형태로 배치되는 복수개의 메모리 셀 각각마다 워드라인 드라이버를 접속하여 각 메모리 셀의 복수개의 워드라인을 구동하는 메모리에 있어서, 상기 워드라인 드라이버는 복수개의 워드라인의 양단마다 풀업용 소자와 풀다운용 소자를 분리하여 각기 접속하고 상기 워드라인 풀업용 소자와 워드라인 풀다운용 소자에 로(ROW) 어드레스를 인가하여 워드라인의 레벨 천이시 중첩 전류 흐름을 방지하도록 구성함을 특징으로 하는 워드라인 드라이버 회로.
- 제1항에 있어서, 워드라인 형성 방향으로 인접하는 메모리 셀간의 인접 워드라인에는 동일한 타입의 풀업용 소자 또는 풀다운용 소자를 접속하여 레이아웃 면적을 줄이도록 구성한 것을 특징으로 하는 워드라인 드라이버 회로.
- 제1항 또는 제2항에 있어서, 풀업용 소자 또는 풀다운용 소자는 모스 트랜지스터로 구성함을 특징으로 하는 워드라인 드라이버 회로.
- 제1항에 있어서, 워드라인에 접속되는 풀다운용 소자에 별도의 서브 워드라인 풀다운용 소자를 병렬 접속하여 구성함을 특징으로 하는 워드라인 드라이버 회로.
