An apparatus including a memory cell, a reference cell, a control unit, coupled to the memory cell and the reference cell, and configured to initiate write processes of the memory cell and the reference cell, and a detection unit, coupled to the reference cell, and configured to detect a write completion of the reference cell. Related methods are also disclosed.

Memory device and testing with write completion detection

The inventive memory circuit comprises a main memory block and a substitution memory block for substitution of defect memory cells, with the substitution memory block being external to the main memory block. The substitution memory block is arranged to substitute at least one bitline-related or wordline-related set of memory cells being connected to the same bitline or wordline, respectively. Furthermore, the inventive memory circuit comprises redirection means for redirecting the access to a memory cell of the at least one respective substituted set of memory cells to the substitution memory block.
