    • Integrated circuit memory device testing circuits and methods compare data on a selected number of the data line outputs of a memory cell array to one another to produce comparison results, in response to a selection signal that indicates the selected number of the data line outputs to be compared to one another. A shared test driver is responsive to the comparison circuit to provide the comparison results to an associated global output line for at least two values of the selection signal that indicate at least two selected numbers of data line outputs to be compared to one another. By sharing test drivers, separate test drivers need not be provided for each selected number of the data line outputs that are compared to one another. The number of test drivers may therefore be reduced so that the area occupied by the testing circuits may be reduced.
    • 集成电路存储器件测试电路和方法将存储器单元阵列的选定数量的数据线输出端上的数据彼此进行比较,以产生比较结果,以响应于选择信号,该选择信号指示所选数量的数据线输出为 相比之下。 共享测试驱动器响应于比较电路,以将比较结果提供给选择信号的至少两个值的关联全局输出线,该至少两个值指示要彼此比较的至少两个选定数量的数据线输出。 通过共享测试驱动程序,不需要为彼此进行比较的每个选定数量的数据线输出提供单独的测试驱动程序。 因此,可以减少测试驱动器的数量,从而可以减少测试电路占据的面积。
