摘要： A level-shifter circuit includes a deep N-tank to insulate the N-channel portions of transistors from the substrate. The circuit is formed on a P-type substrate coupled to reference voltage Vss. A first field-effect transistor has first and second N+ doped regions formed in a third isolating P- doped region. The third doped region is formed in a fourth isolating N- doped region, which is formed in the substrate. A second transistor has first and second N+ doped regions formed in the same isolation regions as those of the first transistor. A third field-effect transistor has first and second P+ doped regions formed in an isolating N- region that is formed in the substrate. A fourth field-effect transistor has first and second N+ doped regions formed in the same isolation N- region as that of the third transistor. The gate of the first transistor is coupled to a first input. The first doped region of the first transistor is coupled to the output and the second doped region of the first transistor is coupled to the negative voltage Vn. The third doped region is coupled to the negative voltage Vn and the fourth doped region is coupled to the supply voltage Vdd. The second transistor is connected in feedback configuration to the first transistor. The gate of the third transistor is coupled to the second input. The first doped region of the third transistor is coupled to the output and the second doped region of the third transistor is coupled to the voltage Vp, which is more positive than the supply voltage Vdd. The fifth doped region of the third transistor is also coupled to the voltage Vp. The fourth transistor is connected in feedback configuration to the third transistor.

摘要： In accordance with one embodiment of the invention, a nonvolatile memory array is encased in a P-tank, and the P-tank encased in a deep N-tank, the two tanks separating the memory array from the substrate and from the other circuitry of the integrated memory circuit. The deep N-tank allows application of a negative voltage of perhaps -8 V to the P-tank encasing the memory array. Application of that negative voltage permits the cells of the memory array to be programmed with voltage pulses having a peak value of about +10 V, rather than the +18 V peak value of prior-art memory arrays. Because the external circuitry, such as the wordline driver circuit, need drive the wordlines at +10 V rather than +18 V, the invention permits construction of that external circuitry using thinner gate insulators and space-saving shorter dimensions.

摘要： An array of electrically programmable semiconductor memory cells of a type having electrically conducting odd and even row lines, left and right column and ground lines and field oxide regions separating adjacent left and right cells. The array has a field plate over the field oxide region which extends underneath both odd and even row lines. A driver is coupled to the odd and even row lines in order to drive one of them to substantially ground potential while the other is driven high to a cell selection voltage.

摘要： Erasable programmable memory cell having a control gate, a row line and bit line is disclosed. Line driving circuitry coupled to the bit line and control gate applies a negative voltage to the bit line during the ERASE mode. The latter voltage is such that the voltage across the control gate, floating gate and drain of the floating gate transistor is sufficiently great to cause charging of the floating gate. The construction of the line driving circuit for applying the various voltages, including the negative erase voltage, to the control gate of the floating gate transistor is also disclosed. The line driving circuit is responsive to a control signal indicating the operating mode of the memory, and further includes blocking transistors so that the V.sub.pp voltage of the write operation is not coupled back to the circuit input which receives the control signal.

摘要： A method of forming a lateral bipolar transistor in a semiconductor substrate of a second conductivity type by an MOS or CMOS process which includes growing a thin insulating layer over the substrate and diffusing a tank region of a first type of conductivity into the semiconductor substrate of a polarity opposite to that of the second conductivity type. A strip of polysilicon is deposited around a region between the emitter area and collector area on a face of the substrate over said oxide. Next an emitter region having the form of a band enclosing an undiffused central region within the polysilicon strip and a collector region located outside of the strip are diffused into the tank. The polysilicon prevents diffusion of implanted impurity into the tank region over which is superimposed the polysilicon. An electrically conducting layer is formed over the emitter and a portion of the polysilicon.By using a strip of polysilicon to limit diffusion of the emitter and collector regions and by forming the emitter contact over both the emitter and polysilicon it is possible to achieve a smaller emitter geometry than is otherwise possible.

摘要： A protective device limiting the current flow through a power transistor 11 in a final stage of an integrated circuit comprises, as part of that circuit, a normally nonconductive shunt transistor 31 which is turned on by a monitoring transistor 22 whenever the collector current I and the collector-emitter voltage V.sub.CE of the power transistor reach values beyond a protective curve 52 plotted on a current/voltage diagram. The base-emitter circuit of the monitoring transistor 22 is connected across an output resistor R.sub.2, in series with the power transistor 11, via a diode 21 of logarithmic conduction characteristic, that diode being also connected across the power transistor in series with a voltage-sensing network. This network includes a voltage divider R.sub.3, R.sub.5 in series with a Zener diode 33, the voltage divider being connected in parallel with a switching transistor 35 whose base is tied to a tap of the divider.
