写入图1是该存贮单元的电路图,其中 abcd 是冷持电流回路,回路中有顺时钟的冷持电流表示1,无电流表示0。在写入线及助写线同时加以激励,于回路abcd 中建立冷持电流。因为助写线中的电流使冷致管变为电阻态,故写入电流通过路径 abcd。如果助写电流在写入电流切断前除去,回路能建立冷持电流。冷持电流的幅度选为 1 is a circuit diagram of the memory cell, where abcd is the cold current loop, the cold current in the loop is 1, and no current is 0. Write lines and write lines at the same time to be motivated, in the circuit abcd build cold holding current. Because the current in the write line causes the cold tube to become resistive, the write current passes through the path abcd. If the write current is removed before the write current is cut off, the circuit can establish a cold current. Select the range of cold current
