| 20090117696 | Fully logic process compatible non-volatile memory cell with a high coupling ratio and process of making the same - A fully logic process compatible non-volatile memory cell has a well on a substrate, a pair of source and drain outside the well, a channel between the source and drain, a control gate in the well, and a floating gate having a first portion above the channel, and a second portion above the well. The control gate includes two regions having opposite conductivity types and a third region between the two regions and under the second portion of the floating gate, and thus eliminates the parasitic depletion capacitor in the coupling path of the cell, thereby improving the coupling ratio. | 05-07-2009 |
| 20090201078 | Single-chip common-drain JFET device and its applications - A single-chip common-drain JFET device comprises a drain, two gates and two source arranged such that two common-drain JFETs are formed therewith. Due to the two JFETs merged within a single chip, no wire bonding connection is needed therebetween, thereby without parasitic inductance and resistance caused by bonding wire, and therefore improving the performance and reducing the package cost. The single-chip common-drain JFET device may be applied in buck converter, boost converter, inverting converter, switch, and two-step DC-to-DC converter to improve their performance and efficiency. Alternative single-chip common-drain JFET devices are also provided for current sense or proportional current generation. | 08-13-2009 |
