ABSTRACT:
Apparatus and methods are provided. A memory device has a memory array comprising primary and redundant portions. A redundancy circuit is coupled to the memory array and is coupled to receive a command signal. The redundancy circuit is adapted to be selectively programmed for selecting a redundant portion of the memory array for programming extra features in response to the command signal when the redundant memory portion is not used for replacing the primary portion.
