Abstract:
A nonvolatile semiconductor storage device has floating-gate memory cells and a memory control circuit which controls them. During programming operation of the memory cells, the memory control circuit makes the potentials at the backgate and source of the memory cells equal. For example, during programming operation of the memory cells, the memory control circuit short-circuits together the backgate and source of the memory cells. For another example, during programming operation of the memory cells, the memory control circuit switches from a state where the potentials at the backgate and source of the memory cells are equal to a floating state.

Claim (Index 8):
The nonvolatile semiconductor storage device according to  claim 1 , wherein the memory cell is a field-effect transistor including a cell well that functions as the backgate, a drain area and a source area formed on a surface of the cell well, a tunnel insulation film formed on a channel area on the surface of the cell well, a floating gate formed on the tunnel insulation film, an oxide insulating film formed on the floating gate, and the control gate formed on the oxide insulating film.
