no current flows and the bitline capacitor maintains its precharged value.Otherwise, if the cell has a VTH lower than VREAD, the current flows and the bitline discharges. Disturb effects alter the memory transistor’s threshold voltage unintentionally during memory access operations. Since it is essential to optimize area consumption, cells are arranged in a matrix, sharing voltages. During the read and program operations,positivevoltagesareappliedtothegatenodesofthememorytransistors, wherein the channel is at a lower potential or even grounded. Therefore, this condition is called gate disturb and is the most common disturb mechanism in NAND Flash memory arrays. The positive voltage is able to cause Fowler–Nordheim tunneling of electrons to the floating gate.
