Abstract:
A method includes replacing an address of a first normal memory cell in a first column of a first memory block with a destination address that is an address of a second normal memory cell in a second column of the first memory block, and reassigning the address of the second normal memory cell in the second column of the first memory block to an address of a first redundancy memory cell in a redundancy block of the memory device.
