    • Integrated circuit memory devices include a column select signal generator which generates a column select signal (CSL) having leading and trailing edges and a preferred timing controller. The timing controller, which is electrically coupled to the column select signal generator and is responsive to at least one latency state signal (e.g., CLy), adjusts the timing of at least one of the leading and trailing edges of the column select signal pulse as a function of the value of the at least one latency state signal. Here, the value of the latency state signal can be adjusted to cause a shift in the timing of the column select signal (CSL) and thereby reduce the likelihood of reading errors. In particular, the timing controller is responsive to a first internal clock signal (e.g., PCLK) and generates first and second control signals as CSLE and CSLD. The column select signal generator is responsive to the first and second control signals. The first control signal is preferably delayed and inverted relative to the first internal clock signal by a first delay and the second control signal is preferably delayed relative to the first internal clock signal by a second delay which is less than the first delay. The timing controller also adjusts the timing of at least one of the leading and trailing edges of the column select signal by adjusting the values of the first and second delays as a function of the value of the at least one latency state signal.
    • 集成电路存储器件包括产生具有前沿和后沿的列选择信号(CSL)的列选择信号发生器和优选的时序控制器。 电气耦合到列选择信号发生器并且响应于至少一个等待时间状态信号(例如,CLy)的定时控制器将列选择信号脉冲的前沿和后沿中的至少一个的定时调整为 是至少一个等待时间状态信号的值的函数。 这里,等待状态信号的值可以被调整以引起列选择信号(CSL)的定时偏移,从而降低读取错误的可能性。 特别地,定时控制器响应于第一内部时钟信号(例如,PCLK),并且产生第一和第二控制信号为+ E,ovs CSLE + EE和CSLD。 列选择信号发生器响应于第一和第二控制信号。 优选地,第一控制信号相对于第一内部时钟信号延迟和反相第一延迟,并且第二控制信号优选地相对于第一内部时钟信号延迟小于第一延迟的第二延迟。 定时控制器还通过调整第一和第二延迟的值作为至少一个等待时间状态信号的值的函数来调整列选择信号的前沿和后沿中的至少一个的定时。

    • Methods and apparatus for controlling output buffer circuitry in a synchronous semiconductor memory device. An internal clock signal is generated and logic provided to provide a control signal that enables that output buffer circuitry for a read operation. An internal clock signal is generated synchronized to the external or system clock signal. An intermediate control signal is triggered by the internal clock signal at a selected number of cycles less than the memory latency period after a read command, and then the control signal for enabling the output buffer is asserted on a subsequent cycle of the internal clock signal, thereby ensuring at least a predetermined minimum time for the output buffer control signal to propagate through the memory device before data is transferred out of the device.
