We introduce the concept of the direct field effect of a neighboring cell transistor on the cell-to-cell interference of NAND Flash cell memory. As the cell size reduces to below 50 nm, the electric field of the adjacent cell transistor directly influences the shallow-trench isolation corner of a selected cell transistor, provoking a significant cell V TH shift. In a way different from how conventional parasitic capacitance-coupling effect alters only the floating gate voltage, the direct field… CONTINUE READING
