Erasing

To abolish a NOR beam corpuscle (resetting it to the "1" state), a ample voltage of the adverse polarity is activated amid the CG and antecedent terminal, affairs the electrons off the FG through breakthrough tunneling. Modern NOR beam anamnesis chips are disconnected into abolish segments (often alleged blocks or sectors). The abolish operation can alone be performed on a block-wise basis; all the beef in an abolish articulation have to be asleep together. Programming of NOR cells, however, can about be performed one byte or chat at a time.
