    • A circuit includes a word line driver for driving a world line and a tracking word line driver for driving a tracking word line. The pulse width of a world line signal on the world line is driven to be larger than that of a tracking world line signal on the tracking world line to assist writing under difficult conditions. Because the tracking word line signal is activated later than the word line signal being activated but is deactivated at the same time with the word line, the pulse width of the word line signal is larger.
    • 电路包括用于驱动世界线的字线驱动器和用于驱动跟踪字线的跟踪字线驱动器。 世界线上的世界线信号的脉冲宽度被驱动为大于跟踪世界线上的跟踪世界线信号的脉冲宽度,以帮助在困难条件下进行写入。 由于跟踪字线信号比字线信号被激活的时间晚,而且与字线同时被去激活,所以字线信号的脉冲宽度较大。
