    • A plurality of single transistor memory cells arrayed in columns with the memory cells within a column connected to one or the other of precharged first and second output lines. An input line connected to the gate of the single transistor causes the first output line to be pulled to a first voltage when the cell is programmed a "true" and to be pulled to a second voltage when the cell is programmed a "complement". A pair of cross-coupled transistors connected between the first and second output lines of a column cause the second output line to be maintained at the precharged voltage when programmed a "true" and causes the first output line to be maintained at a precharged voltage when programmed a "complement".
    • 多个单个晶体管存储单元排列成列,其中存储单元位于连接到预充电的第一和第二输出线之一或另一个的列内。 连接到单个晶体管的栅极的输入线使得当单元被编程为“真”时将第一输出线拉至第一电压,并且当单元被编程为“补码”时将其拉至第二电压。 连接在列的第一和第二输出线之间的一对交叉耦合晶体管使第二输出线在编程为“真”时保持在预充电电压,并且使第一输出线保持在预充电电压,当 编程为“补充”。
