Abstract
The disclosure relates to a method of reading and writing memory cells, each including a charge accumulation transistor in series with selection transistor, including applying a selection voltage to a gate of the selection transistor of the memory cell; applying a read voltage to a control gate of the charge accumulation transistor of the memory cell; applying the selection voltage to a gate of the selection transistor of a second memory cell coupled to the same bitline; and applying an inhibition voltage to a control gate of the charge accumulation transistor of the second memory cell, to maintain the transistor in a blocked state.
