WebTo set the memory cells to the ‘1’ state, erase pulses with a high electric field are applied to the sector to remove electrons from the floating gate of every memory cell in the sector/block. Then the Verify operation sequentially reads off all of the address locations in the sector/block to check whether they have all been erased to ‘1’. Web\$\begingroup\$ One question would be if blocks routinely "go bad" in the sense of suddenly reading back longstanding data erroneously, or if they "go bad" in the sense of being unable to write new data and read it back reliably after an erase has been performed to re-use that block. \$\endgroup\$ – Chris Stratton
