    • PURPOSE: A bit line sense amplifier control circuit and a semiconductor memory device including the same are provided to improve an operation speed by quickly recording data in a write operation for requiring data toggle. CONSTITUTION: A bit line sense amplifier control circuit includes a driving control signal generator(110), a bit line sense amplifier driver(120), and a column selection control signal generator(105). The driving control signal generator outputs first to fourth sense amplifier driving signals in response to a sense amplifier enable signal and a column selection control signal. The column selection control signal generator generates a column selection control signal in response to a read command and a column selection signal.

    • PURPOSE: A domain crossing circuit of a semiconductor memory apparatus is provided to implement a highly reliable operation in a high speed circuit by being synchronized with a clock edge. CONSTITUTION: A sampler(200) responds to a clock signal and delays an internal input signal by a certain interval, and it supplies a sampling internal signal and an edge information signal. An output stage responds to the edge information signal and synchronizes the internal signal with the clock signal to output a final output signal. A trigger signal generation block(220) samples the internal input signal at the falling edge and rising edge of the clock signal to supply a plurality of trigger signals. A combination block(240) selectively synchronizes the internal input signal at the falling edge and rising edge of the clock signal to supply a sampling internal signal. A clock edge information block(260) supplies the edge information of the clock which is an output reference of the sampling internal signal as edge information.
    • 目的:提供半导体存储装置的域交叉电路,通过与时钟边沿同步,在高速电路中实现高度可靠的操作。 构成:采样器(200)响应时钟信号并将内部输入信号延迟一定间隔,并提供采样内部信号和边沿信息信号。 输出级响应边沿信息信号,并将内部信号与时钟信号同步以输出最终的输出信号。 触发信号生成块(220)在时钟信号的下降沿和上升沿对内部输入信号进行采样以提供多个触发信号。 组合块(240)在时钟信号的下降沿和上升沿选择性地同步内部输入信号以提供采样内部信号。 时钟边缘信息块(260)将作为采样内部信号的输出基准的时钟的边沿信息作为边缘信息提供。
