    • A class AB amplifier (400) is disclosed, having a first input node (402), a second input node (404), and an output node (406). A push-pull input stage (412) includes cross-coupled pairs of transistors, which form a charge current path and a discharge current path. When the voltage at the first input node (402) is greater than the voltage at the second input node (406), the amount of current drawn in the charge current path increases, and the amount of current drawn in the discharge current path decreases. When the voltage at the first input node (402) is less than the voltage at the second input node (404), the amount of current in the charge current path decreases while the amount of current in the discharge path increases. A first and fourth current mirror (422 and 428) are coupled to the charge current path, and a second and third current mirror (424 and 426) are coupled to the discharge current path. In response to increases in the amount of current drawn in the charge current path, the first current mirror (422) drives a discharge node (432) to a charge voltage, and the fourth current mirror (428) drives a charge node (434) to a charge voltage. In response to increases in the amount of current drawn in the discharge current path, the second current mirror (424) drives the discharge node (432) to discharge voltage, and the third current mirror (426) drives the charge node (434) to a discharge voltage. An output driver (430) charges the output node (406) when the charge node (434) is at the charge voltage, and discharges the output node (406) when the discharge node (432) is at the discharge voltage.

    • In order to select between normal memory components and redundant memory components in an integrated circuit memory device, a logic signal (ENABLE/DISABLE) indicative of the requirement to access the normal memory components or to access the redundant memory components is generated in response to an applied address signal group. When the logic signal has a first logic state, power from dynamic power distribution unit (35) is applied to the output stages (32) of the column addressing apparatus (11,32) activating the normal column conducting paths and power is withheld from the output stages (37) which would otherwise activate the redundant column conducting paths. When the logic signal (ENABLE/DISABLE) has a second logic state, power is applied to the output stages 37 activating the redundant column conducting paths and withheld from the output stages 32 which would otherwise activate the normal column conducting paths. By directly controlling the power applied to the output stages (32,37), the logical combination of control signal and other parameter-bearing signals is avoided, thereby resulting in a faster response to the changes in the logic signal.
    • 为了在集成电路存储器件中的正常存储器组件和冗余存储器组件之间进行选择,响应于一个逻辑信号(ENABLE / DISABLE),指示访问正常存储器组件或访问冗余存储器组件的要求 应用地址信号组。 当逻辑信号具有第一逻辑状态时,来自动态功率分配单元(35)的功率被施加到激活正常列导通路径的列寻址设备(11,32)的输出级(32),并且从 输出级(37),否则将激活冗余列传导路径。 当逻辑信号(ENABLE / DISABLE)具有第二逻辑状态时,功率被施加到输出级37,激活冗余列传导路径,并从输出级32保留,否则将激活正常的列传导路径。 通过直接控制施加到输出级(32,37)的功率,避免了控制信号和其他参数承载信号的逻辑组合,从而导致对逻辑信号的变化的更快响应。
