Abstract
A semiconductor memory device and a method for mending a failed memory cell by directly programming a fuse memory cell. Using a tester to program the fuse memory cell directly, a laser machine is not required. In addition, to move the wafer for fuse allocation is not required either, so that the consumption in time and cost can be greatly reduced. Even after the package is complete, the repairing work can still be performed. In addition, whether the voltage source is connected or disconnected, the failed address information is kept and stored without being lost. A self-repair for self-test can thus be applied.
