作者研制了一种具有涡旋过渡存储单元和电阻耦合驱动器的约瑟夫森4Kbit RAM。该RAM采用1.5 μ m Nb工艺制造，具有约21000个Nb/AlO/sub x//Nb约瑟夫森结。在4Kbit RAM芯片中，实验获得了380 ps的存取时间、98.6%的位成品率和9.5mW的功耗。>
The authors have developed a Josephson 4 Kbit RAM with vortex transitional memory cells and resistor coupled drivers. The RAM is fabricated by 1.5 mu m Nb technology with approximately 21000 Nb/AlO/sub x//Nb Josephson junctions. 380 ps access time, 98.6% bit yield, and 9.5 mW power dissipation have been experimentally obtained in the 4 Kbit RAM chip. >
