Abstract
A non-volatile memory including a plurality of memory cells configured to store data and a plurality of redundant memory cells configured to be used for functionally replacing defective memory cells. The memory further includes a protection register comprising storage elements configured to store configuration data of the memory device. The storage elements of the protection register are redundant memory cells not being used to replace defective memory cells.
Claims21
A non-volatile memory including:
- a plurality of memory cells configured to store data;
