Abstract: A method of operating a memory cell that comprises first and second regions spaced apart in a substrate with a channel region therebetween, a floating gate disposed over the channel region and the fir region, a control gate disposed over the channel region and laterally adjacent to the floating gate with a portion disposed over the floating gate, and a coupling gate disposed over the first region and laterally adjacent to the floating gate. A method of erasing the memory cell includes applying a positive voltage to the control gate and a negative voltage to the coupling gate. A method of reading the memory cell includes applying positive voltages to the control gate, to the coupling gate, and to one of the first and second regions.

Abstract: Examples for ultra-precise tuning of a selected memory cell are disclosed. In one example, a method of programming a first memory cell in a neural memory to a target value is disclosed, the method comprising programming a second memory cell by applying programming voltages to terminals of the second memory cell; and determining if an output of the first memory cell has reached the target value.
