    • A semiconductor memory device including a data bus inversion (DBI) determination unit, a first inverter, a cyclic redundancy check (CRC) calculation unit, a second inverter, and a DQ pin. The DBI determination unit is configured to determine whether to perform DBI based on first data on a main data line and configured to generate DBI data. The first inverter is configured to invert or non-invert the first data according to the DBI data to generate second data. The CRC calculation unit is configured to generate CRC data based on the second data and the DBI data. The second inverter is configured to invert or non-invert the first data according to the DBI data to generate third data. The DQ pin is configured to output the third data externally.
    • 一种包括数据总线反相(DBI)确定单元,第一反相器,循环冗余校验(CRC)计算单元,第二反相器和DQ引脚的半导体存储器件。 DBI确定单元被配置为基于主数据线上的第一数据来确定是否执行DBI并且被配置为生成DBI数据。 第一反相器被配置为根据DBI数据反转或不反转第一数据以产生第二数据。 CRC计算单元被配置为基于第二数据和DBI数据生成CRC数据。 第二反相器被配置为根据DBI数据反转或不反转第一数据以产生第三数据。 DQ引脚配置为从外部输出第三个数据。

    • Integrated circuit memory devices having data input and output lines in a column direction and circuits and methods for repairing faulty cells are provided. A column select line according to the present invention extends along a row direction. Data input and output lines extend along a column direction. In repairing faulty cells, the column having the faulty cells is not directly replaced by a redundancy column but rather is replaced by an adjacent column. Thus, an increase of layout area upon increase of the input and output lines can be reduced. The operational current also may be reduced. Differences in parasitic capacitance from the respective columns to global input and output lines also may be reduced. Also, the faulty cells may be repaired without lowering the speed at which data is input and output during the redundancy operation.
    • 提供具有沿列方向的数据输入和输出线的集成电路存储器件以及用于修复故障单元的电路和方法。 根据本发明的列选择线沿行方向延伸。 数据输入和输出线沿列方向延伸。 在修复故障单元时,具有故障单元的列不直接由冗余列替换,而是由相邻列替代。 因此,可以减少输入和输出线增加时的布局面积的增加。 操作电流也可能降低。 寄生电容从各列到全局输入和输出线的差异也可能会降低。 此外,可以修复故障小区而不降低在冗余操作期间输入和输出数据的速度。
