Abstract

본 발명은 비밀번호 검색 기능을 가진 메모리카드에 관한 것으로, 종래의 메모리카드는 일반사용자들 누구나가 읽기 및 쓰기를 할 수 있기 때문에 메모리내의 데이타가 손상되거나 도난을 당할 수 있는 문제점이 있었다. 본 발명은 이러한 종래의 문제점을 해결하기 위해 비밀번호를 저장하기 위한 비밀번호기억부와; 상기 비밀번호 기억부의 출력 데이타신호와 메인메모리로부터 출력되는 사용자의 외부입력 데이타신호를 비교하여 그에 따른 신호를 출력하는 비교부와; 상기 비교부의 출력신호에 따라 그에따른 제어신호를 출력하는 스위칭제어부와; 상기 스위칭제어부의 제어신호에 따라 온/오프되어 외부로부터의 제어신호를 메인메모리에 전달하는 스위칭부로 구성한 비밀번호 검색 기능을 가진 메모리카드를 창안한 것으로, 이의 작용을 통해 즉, 메모리카드에 비밀번호 검색기능을 부가함으로써 비밀번호를 정확하게 입력할 수 있는 특정 사용자만이 메모리카드를 사용할 수 있어 메인메모리내의 데이타 등을 안전하게 보존할 수 있는 효과가 있다.The present invention relates to a memory card having a password retrieval function, and a conventional memory card has a problem in that data in the memory may be damaged or stolen because all users can read and write. The present invention provides a password storage unit for storing a password to solve such a conventional problem; A comparison unit for comparing the output data signal of the password storage unit with the external input data signal of the user output from the main memory and outputting a corresponding signal; A switching controller for outputting a control signal according to the output signal of the comparator; Invented a memory card having a password retrieval function consisting of a switching unit that is turned on / off according to the control signal of the switching control unit to transfer a control signal from the outside to the main memory, through the action of that, that is, the password retrieval function By adding, only certain users who can enter the password correctly can use the memory card, so that the data in the main memory can be securely stored.
