← ScienceWhich outcome results during semiconductor flash memory cell erase?
A)Electrons tunneling from floating gate✓
B)Holes accumulating within the substrate
C)Positive charge carriers recombining
D)Increased gate oxide dielectric breakdown
💡 Explanation
Electrons tunnel from the floating gate to the source because Fowler-Nordheim tunneling is enhanced by a strong electric field; therefore the cell is erased as charge is removed, rather than accumulating holes in the substrate.
