Title: Memory cell
Inventor: TAGO HARUYUKI
IPC: H01L21/8244
Filed: 1983-11-22
Abstract: PURPOSE:To obtain a memory cell having the small number of component elements and a small occupied area in spite of a simultaneous reading function for two address by connecting each output of intersection-connected invertors to a source terminal of a transistor, connecting its gate terminal to separate word lines and connecting a drain terminal to separate data lines so as to use. CONSTITUTION:In order to write data to a cell, a ''0'' and ''1'' level, or an ''1'' and ''0'' level are fed to two data lines 20 and 21, then two word lines 30 and 31 are both set to an 1 level. In such operation, transistors 5 and 6 are turned on, and the voltage of the data line is written in nodes 9 and 10. The reading out operation set the data line at the reading side first to ''1'' level. Then, when the data line to execute reading is set to the ''1'' level, the contents of a cell appears on the data line. Since other pair of a data line and a word line can execute a reading operation independently, they operate as a two-port memory.

Abstract: PURPOSE:To endure a dry etching process, and prevent the overetching at the time of processing an upper electrode, by a method wherein, after the upper electrode to form a Josephson junction is processed, a specific metal oxide is used as an interlayer insulating film on the part except the upper electrode forming region. CONSTITUTION:An upper electrode 4 to form a Josephson junction, the side wall of a tunnel barrier 3, a lower electrode 2, and a part of the side wall of the lower electrode are completely covered with an interlayer insulating film 5 of A2O3.
