    • An integrated circuit having a memory which includes an array of data storage cells is provided with a redundant array and a signal-directing circuit. A row or column signal for a defective cell, if present, as well as each successively higher row or column signal, is directed to sequentially higher address locations in the array to thereby avoid the defective cell address location. The last row or column signal is directed to the address location of the redundant array. A fuse is preferably associated with each row or column signal which may be selectively melted to direct the row or column signals. The array can be logically divided into subarrays each having an associated redundant array so that defects in each subarray can be accommodated.
    • 具有包括数据存储单元阵列的存储器的集成电路设置有冗余阵列和信号引导电路。 如果存在缺陷单元的行或列信号以及每个连续更高的行或列信号,则被排列在阵列中的顺序地更高的地址位置,从而避免了缺陷单元地址位置。 最后一行或者列信号被引导到冗余阵列的地址位置。 保险丝优选地与可以选择性地熔化以指导行或列信号的每行或列信号相关联。 阵列可以在逻辑上划分为每个具有相关冗余阵列的子阵列,从而可以容纳每个子阵列中的缺陷。
