Each memory cell of the NAND flash memory device comprises a floating gate, a control gate connected to a wordline and receives a control voltage therefrom to induce a programming charge on the floating gate, and a bitline adapted to apply an erase voltage to deplete the floating gate of the programming charge. Each memory cell further includes circuitry for modulating the erase voltage according to the level of the programming charge on its floating gate."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Flash memory device and method of operation","description":"A NAND flash memory device and method of erasing memory cells thereof, wherein each cell is only subjected to the level of erase voltage needed to restore its nominal “erased” state.
