Web12 de jul. de 2015 · The default state of flash memory cells (a single-level NOR flash cell) is 1 because floating gates carry no negative charges. Erasing a flash-memory cell (resetting to a 1) is achieved by applying a voltage across the source and control gate (word line). The voltage can be in the range of -9V to -12V. And also apply around 6V to the source.
