  • Patent number: 11495314
    Abstract: A semiconductor device is provided, which contains a memory bank including M primary word lines and R replacement word lines, a row/column decoder, and an array of redundancy fuse elements. A sorted primary failed bit count list is generated in a descending order for the bit fail counts per word line. A sorted replacement failed bit count list is generated in an ascending order of the M primary word lines in an ascending order. The primary word lines are replaced with the replacement word lines from top to bottom on the lists until a primary failed bit count equals a replacement failed bit count or until all of the replacement word lines are used up. Optionally, the sorted primary failed bit count list may be re-sorted in an ascending or descending order of the word line address prior to the replacement process.

  • Patent number: 11482268
    Abstract: Apparatuses and techniques for compensating for noise, such as a leakage current, in a memory array are described. Leakage currents may, for example, be introduced onto a digit line from unselected memory cells. In some cases, a compensation component may be coupled with the digit line during a first phase of a read operation, before the target memory cell has been coupled with the digit line. The compensation component may sample a current on the digit line and store a representation of the sampled current. During a second phase of the read operation, the target memory cell may be coupled with the digit line. During the second phase, the compensation component may compensate for leakage or other parasitic effects by outputting a current on the digit line during the read operation based on the stored representation of the sampled current.
