Abstract
동작시의 소비전류가 큰 문제와 동작스피드가 늦인 문제를 제거하고 소비전류가 적고 또한 동작스피드가 빠른 디코더 회로를 제공하는 것이다.It is possible to provide a decoder circuit which eliminates the problem of large current consumption during operation and a problem of late operating speed and low current consumption and fast operating speed.
제1도는 본 발명에 의한 디코더 회로의 실시예를 표시하는 회로도다.1 is a circuit diagram showing an embodiment of a decoder circuit according to the present invention.
제2도는 디코더 회로는 NAND10∼NAND1m와 INV10∼INV1m에 의해 구성되어 있다.2, the decoder circuit is composed of NAND10 to NAND1m and INV10 to INV1m.
또, 제2의 디코더 회로는 NAND00∼NAND03와 INV00∼INV03에 의해 구성되어 있다.The second decoder circuit is composed of NAND00 to NAND03 and INV00 to INV03.
다시, 단위 디코더회로 DCM은 제1의 디코더 회로와 제2의 디코더 회로와의 출력의 교점에 매트릭스 상으로 배치되어 있다.Again, the unit decoder circuit DCM is arranged in a matrix at the intersection of the outputs of the first decoder circuit and the second decoder circuit.
제1의 디코더 회로는 NAND출력 - D0∼Dm와 INV출력 D0∼Dm에 의해 단위 디코더 회로 DCM의 트랜스퍼 게이트를 구동하고, 구동된 DCM는 제2의 디코더 회로로부터의 출력을 출력신호로서 출력한다.The first decoder circuit drives the transfer gate of the unit decoder circuit DCM with the NAND outputs-D0-Dm and the INV outputs D0-Dm, and the driven DCM outputs the output from the second decoder circuit as an output signal.
