The present invention provides an electromagnetic component formed from adjacent conducting layers of a multi-layer PCB and two additional conducting layers in contact with the PCB. The inventive component includes one or more winding turns formed by connecting the multiple layers of the multi-layer PCB with conductive vias and by connecting the additional conducting layers to respective top and bottom surfaces of the PCB. In one embodiment, one of the conducting layers is soldered to a top conducting layer of the PCB and the other of the conductive layers is soldered to a bottom conducting layer of the PCB, effectively increasing the cross-sectional area of the top and bottom winding layers. In another embodiment, the additional conducting layers are separated from the adjacent conducting PCB layers by a layer of insulation, permitting the additional conducting layers to form separate winding turns. The inventive winding stack can be surface mounted to a PCB, and can be used as an inductor, or in other electromagnetic devices. The winding thus constructed is capable of accepting larger currents with lower resulting temperature increases than windings formed only from PCBs, and are less expensive to manufacture than PCB-only windings.

Several 2D and 3D HiNAND flash memory arrays with 1-level or 2-level broken BL-hierarchical structures are provided for Multiple Whole-WL and All-BL simultaneous operations in Dispersed Blocks. The global bit line (GBL) is divided to multiple 1 (top)-level broken metal2 GBLs plus optional lower-level broken metal1 local bit lines (LBLs). A preferred Vinhibit supply higher than Vdd can be selectively supplied via horizontal metal0 power line LBLps to charge selected broken GBLs / LBLs which can also be selectively discharged via a String source line. Charge-sharing technique for precharging and discharging of broken GBL / LBL capacitors for NAND cell data sensing is used in Read and Verify operations with reduced power consumption and latency. Recall technique to restore the desired Program Data stored in the broken GBL / LBL capacitors is used for Multiple-WL and All-BL Program and Program-Verify operation with reduced program current for highest program yield superior P / E cycles.

Electrostatic discharge (ESD) protection is provided for an integrated circuit. Snap back from a lower initial critical voltage and critical current is provided, as compared to contemporary designs. A dynamic region having doped regions is formed on a substrate, interconnects contacting the dynamic region. The dynamic region includes an Nwell region, a Pwell region and shallow diffusions, defining a PNP region, an NPN region and a voltage Breakdown region. In an aspect, the Nwell region includes a first N+ contact, a first P+ contact and an N+ doped enhancement, while the Pwell region includes a second N+ contact, a second P+ contact and a P+ doped enhancement. The N+ doped enhancement contacts the P+ doped enhancement forming the breakdown voltage region therebetween, in one case forming a buried breakdown voltage junction. Independent control is provided over breakdown voltage, NPN critical voltage, NPN critical current and PNP critical current, by varying doping levels, widths and positioning of various doping regions.

The present invention provides an ESD protection circuit electrically connected between a high voltage power line and a low voltage power line, and the ESD protection circuit includes a bipolar junction transistor (BJT) and a trigger source. A collector of the BJT is electrically connected to the high voltage power line, and an emitter and a base of the BJT are electrically connected to the low voltage power line. The trigger source is electrically connected between the base of the BJT and the high voltage power line.
