    • Data selector circuit including a plurality of data registers connected in parallel via corresponding output buffers to a plurality of output drivers, wherein a decoder and selector portion is interposed between the output buffers and the output drivers for selectively providing one of a plurality of serial data output sequences from the data registers to the output drivers rather than a parallel data output format from the plurality of data registers which would otherwise occur. The decoder and selector portion is controlled by a partial address buffer which is provided with serial sequence selection data. Upon decoding the serial sequence selection data of the partial address buffer, a plurality of MOS transistors included in the selector portion are rendered conductive in sequence in response to respective control signals applied to the gates thereof to connect the plurality of data registers via their output buffers to respective output drivers in a sequence determined by the decoded selection data of the partial address buffer for serial data output in the selected serial data output sequence.

    • A sense amplifier circuit is described for switching plural inputs at high speed. At least two transistors for providing at least two true input signals are connected in parallel and have their source terminals connected to a common node from which an output signal may be read. Similarly, at least two other transistors for providing the inverse of the true input signals are connected in parallel and their source terminals are connected to another common node from which an inverse of the output signal may be read. The common nodes are then precharged to the same voltage. True and inverse input signals are applied to their respective transistors through transfer gates where all the true input signals are greater than their respective inverse signals. Therefore, the on-resistance of each of the transistors to which a true input is applied have a higher on-resistance than the associated transistors to which an inverse input is applied. Current flow then rapidly decreases through the transistors transmitting the inverse input signal as current is switchably applied to the transistors transmitting the true input signals.
    • 描述了用于高速切换多个输入的读出放大器电路。 用于提供至少两个真实输入信号的至少两个晶体管并联连接,并且它们的源极端子连接到可从其读取输出信号的公共节点。 类似地,用于提供真实输入信号的反相的至少两个其他晶体管并联连接,并且它们的源极端子连接到另一个公共节点,从该公共节点可以读取输出信号的反相。 然后将公共节点预充电到相同的电压。 真和反输入信号通过传输门施加到它们各自的晶体管,其中所有的真实输入信号都大于它们各自的反相信号。 因此,施加真实输入的每个晶体管的导通电阻具有比施加反相输入的相关联的晶体管更高的导通电阻。 随着电流可切换地施加到传输真实输入信号的晶体管,电流随后通过反相输入信号传输的晶体管迅速减小。
