WebThe transition to 5b/cell (PLC) will be another steppingstone to accelerating bit density growth and expanding Flash storage to wider markets, where a lower cost at a reasonable performance is the paramount requirement. WebThese defects change the potential energy between floating gate and substrate and reduces the program/erase efficiency during operations. As trapped charges accumulate in the tunneling oxide layer, the programming characteristics may also shift. ...

WebA NAND cell is a transistor consisting of a control gate on top and a floating gate sandwiched between two isolation layers with a channel linking source and drain below. Applying a voltage across the control gate attracts electrons in the channel to tunnel through the first isolation layer and into the floating gate.

WebIt results from capacitive coupling via parasitic capacitors around the floating gate. The coupling ratio defined in the previous works should be modified to include the floating-gate interference. In a 0.12-μm design-rule NAND flash cell, the floating-gate interference corresponds to about 0.2 V shift in multilevel cell operation.
