    • A write driver circuit of a semiconductor memory to provide an unmuxed bit line scheme which reduces a height of an unmuxed Y-path so as to reduce an area of a chip in the memory. The write driver circuit can include an input latch circuit which latches input data, in response to an input enable signal; a first write driver which receives write data output from the input latch circuit, in response to a write enable signal, and outputs data to a bit line; and a second write driver which receives inverse data of the write data output from the input latch circuit, in response to the write enable signal, and outputs data to a complementary bit line, wherein the first and second write drivers have a NAND gate type structure and function as a write driver and a precharge driver.
    • 一种半导体存储器的写入驱动器电路,用于提供一种未复位的位线方案,其减小了未变形的Y路径的高度,以便减小存储器中芯片的面积。 写入驱动器电路可以包括输入锁存电路,其响应于输入使能信号锁存输入数据; 第一写驱动器,响应于写使能信号接收从输入锁存电路输出的写数据,并将数据输出到位线; 以及第二写入驱动器,其响应于所述写入使能信号接收从所述输入锁存电路输出的写入数据的反向数据,并将数据输出到互补位线,其中所述第一和第二写入驱动器具有与非门类型结构 并用作写入驱动器和预充电驱动器。
