Abstract
Description
Claims (5)
- 어드레스 공간이 블록으로 분할되는 DRAM에 있어서,메모리 셀을 가지는 메모리 블록;펄스를 가지는 RAS를 공급하는 제어기를 포함하며;상기 메모리 블록은 각각 시작과 끝을 가지며, 상기 RAS로부터 유도된 활성화 신호에 의해 활성화되며, 상기 각각의 메모리 블록은 독립 활성화 신호를 가지며; 그리고상이한 메모리 블록에 대한 상기 활성화 신호는 상기 RAS 펄스로부터 상기 활성화 신호의 시작과 끝을 각각 유도함으로써 시간적으로 일부 중첩되어 상기 상이한 메모리 블록에 차례로 공급되며, 얻어진 데이터 레이트는 단지 하나의 메모리 블록의 활성화에 비해 적어도 2개의 상기 상이한 메모리 블록이 부분적으로 동시에 활성화됨으로써 증가되는 것을 특징으로 하는 DRAM.
- 제 1항에 있어서, 활성화 신호의 지속 시간이 상기 RAS로부터 유도되는 것을 특징으로 하는 DRAM.
- 제 1항에 있어서, 상기 활성화 신호의 지속 시간이 내부 타이머에 의해 공급되는 것을 특징으로 하는 DRAM.
- 제 1항에 있어서, 상기 RAS는 펄스 주기 및 상기 펄스 주기보다 훨씬 짧은 예비 충전 시간 주기를 포함하는 것을 특징으로 하는 DRAM.
- 어드레스 공간이 블록으로 분할되는 DRAM에 있어서,메모리 셀을 가지는 메모리 블록;펄스를 가지는 RAS를 공급하는 제어기; 및상기 활성화 신호의 각각의 주기를 결정하는 내부 타이머를 포함하며;상기 메모리 블록은 각각 시작과 끝을 가지며, 상기 RAS로부터 유도된 활성화 신호에 의해 활성화되며, 상기 각각의 메모리 블록은 독립 활성화 신호를 가지며;상이한 메모리 블록에 대한 상기 활성화 신호는 상기 RAS 펄스로부터 상기 활성화 신호의 시작을 유도함으로써 시간적으로 일부 중첩되어 상기 상이한 메모리 블록에 차례로 공급되며, 얻어진 데이터 레이트는 단지 하나의 메모리 블록의 활성화에 비해 적어도 2개의 상기 상이한 메모리 블록이 부분적으로 동시에 활성화됨으로써 증가되는 것을 특징으로 하는 DRAM.
