Abstract

A memory system includes memory cells arranged in sectors. A decoder corresponding to a sector disables memory cells having a defective top gate. The decoder may include a low voltage or high voltage latch for the disabling. A top gate handling algorithm is included. The memory system may include dynamic top gate coupling. A programming algorithm and waveforms with top gate handling is included.
