| 10. A memory device comprising:
a memory array including a plurality of layers of memory cells stacked vertically above one another in a single chip;
a detection circuit operative to detect, while a memory cell of the memory array is being programmed, when the memory cell
is in a programmed state; and
a memory cell protection circuit coupled to said detection circuit and the memory, said memory cell protection circuit being
operative to protect the memory cell of the memory array against excessive electrical energy at least while the memory cell
is being programmed.
