| 2000 | Invention patented by Toshiaki Kirihata and Alexander Mitwalsky on March 23th, 2000. Abstract: According to one aspect of the invention, there is provided a method for refreshing memory cells in semiconductor memories. The method includes the steps of providing a semiconductor memory having memory cells and redundancy memory cells in at least one memory array and an associated redundancy memory array, respectively. The memory cells and the redundancy memory cells are independently refreshed, using addresses generated by a row address counter and a redundancy address counter, respectively. The method optionally includes the step of disabling redundancy wordlines coupled to unused redundancy memory cells, using a master fuse signal corresponding to a master fuse of the semiconductor memory. |
