Claims (6)
- 무단으로 데이터를 엑세스하는 것을 방지한 전자 인코딩 장치에서 비휘발성 메모리의 데이터를 읽는 방법에 있어서,제 1 데이터 세트를 비휘발성 메모리에 기입하고;기입할 때에 비휘발성 메모리에 적용되는 입력 전압을 나타내는 전압 측정 신호를 생성하고;전압 측정 신호를 평가하여 기입이 성공적으로 수행되었는가를 결정하고;그 결정에 의거하여 비휘발성 메모리로부터 데이터를 읽는 것을 포함하는 것을 특징으로 하는 방법.
- 무단으로 데이터를 엑세스하는 것을 방지한 전자 인코딩 장치에서 비휘발성 메모리의 데이터를 읽는 시스템에 있어서,제 1 데이터 세트를 비휘발성 메모리에 기입하는 수단;기입할 때에 비휘발성 메모리에 적용되는 입력 전압을 나타내는 전압 측정 신호를 생성하는 수단;전압 측정 신호를 평가하여 기입이 성공적으로 수행되었는가를 결정하는 수단;그 결정에 의거하여 비휘발성 메모리로부터 데이터를 읽는 수단을 포함하는 것을 특징으로 하는 시스템.
- 비휘발성 메모리;비휘발성 메모리를 엑세스 할 수 있는 컨트롤러;비휘발성 메모리를 엑세스 할 수 있는 인코더 로직;컨트롤러와 전자 통신 할 수 있는 입력 로직;비휘발성 메모리와 전자 통신 할 수 있는 출력 로직;비휘발성 메모리의 읽기를 활성화 시키기 위하여 비휘발성 기입 전압에 반응하여 신호를 제공하는 전위 측정 회로를 포함 하는 것을 특징으로 하는 전자 인코딩 장치.
- 제 1항에서,상기 전위 측정 회로가 각각의 일차 임계 전압(first threshold voltage)을 갖는 직렬로 연결된 한 쌍의 P채널 트랜지스터;제 2 임계 전압(second threshold voltage)을 갖는 N채널 트랜지스터;한 쌍의 P채널 트랜지스터와 직렬로 연결된 N채널 트랜지스터;컨트롤러와 N채널 트랜지스터의 입력(source) 사이를 잇는 전압 측정 신호 경로를포함하는 것을 특징으로 하는 전자 인코딩 장치
- 무단으로 데이터를 엑세스하는 것을 방지한 전자 인코딩 장치에서 비휘발성 메모리의 데이터를 읽는 방법에 있어서,제 1 데이터 세트를 비휘발성 메모리에 기입하고;기입할 때에 비휘발성 메모리에 적용되는 입력 전압을 나타내는 전압 측정 신호를 생성하고;전압 측정 신호를 평가하여 기입이 성공적으로 수행되었는가를 결정하고;그 결정에 의거하여 비휘발성 메모리로부터 데이터를 읽는 것을 특징으로 하는 방법.
- 비휘발성 메모리;비휘발성 메모리를 엑세스 할 수 있는 컨트롤러;비휘발성 메모리를 엑세스 할 수 있는 인코더 로직;컨트롤러와 전자 통신 할 수 있는 입력 로직;비휘발성 메모리와 전자 통신 할 수 있는 출력 로직;비휘발성 메모리의 읽기를 활성화 시키기 위하여 비휘발성 기입 전압에 반응하여 신호를 제공하는 전위 측정 회로를 포함하는 것을 특징으로 하는 전자 인코딩 장치.
