摘要: An off-chip driver circuit including an enhancement PFET, a depletion PFET, a depletion NFET and an enhancement NFET connected in series. The large enhancement PFET and large enhancement NFET turn off the OCD in tri-state and to turn off the unused half of the OCD to prevent overlap current when driving a ‘0’ or a ‘1’. A first gate signal is applied to the gate of the enhancement PFET and a second gate signal is applied to the enhancement NFET. A fixed voltage is connected to the gate of the depletion NFET and ground to gate of the depletion PFET. An output signal is obtained from a node between the depletion PFET and depletion NFET devices. In another embodiment, a reflection/overshoot sensor 60 is added. The output of sensor is connected to the body of a depletion PFET and an NFET. The feedback from sensor is such that the threshold voltage of the depletion devices are made more positive if the sensor detects that the output is being over-driven. A more positive threshold voltage will reduce the driver's IDS, but leaves the device in the linear mode.

摘要: Wafer test and burn-in is accomplished with state machine or programmable test engines located on the wafer being tested. Each test engine requires less than 10 connections and each test engine can be connected to a plurality of chips, such as a row or a column of chips on the wafer. Thus, the number of pads of the wafer that must be connected for test is substantially reduced while a large degree of parallel testing is still provided. The test engines also permit on-wafer allocation of redundancy in parallel so that failing chips can be repaired after burn-in is complete. In addition, the programmable test engines can have their code altered so test programs can be modified to account for new information after the wafer has been fabricated. The test engines are used during burn-in to provide high frequency write signals to DRAM arrays that provide a higher effective voltage to the arrays, lowering the time required for burn-in. Connections to the wafer and between test engines and chips are provided along a membrane attached to the wafer. Membrane connectors can be formed or opened after the membrane is connected to the wafer so shorted chips can be disconnected. Preferably the membrane remains on the wafer after test, burn-in and dicing to provide a chip scale package. Thus, the very high cost of TCE matched materials, such as glass ceramic contactors, for wafer burn-in is avoided while providing benefit beyond test and burn-in for packaging.

The controlling logic chip coordinates external communication with the N memory chips such that a single memory chip architecture with N.times.M memory devices appears at the cube's I/O pins.

摘要: A vertical Field Effect Transistor (FET) that may be an N-type FET (NFET) or a P-type FET (PFET); a multi-device vertical structure that may be two or more NFETs or two or more PFETs; logic gates including at least one vertical FET or at least one multi-device vertical; a Static Random Access Memory (SRAM) cell and array including at least one vertical FET; a memory array including at least one such SRAM cell; and the process of forming the vertical FET structure, the vertical multi-device (multi-FET) structure, the logic gates and the SRAM cell. The vertical FETs are epitaxially grown layered stacks of NPN or PNP with the side of a polysilicon gate layer adjacent the device's channel layer. The multi-FET structure may be formed by forming sides of two or more gates adjacent to the same channel layer or, by forming multiple channel layers in the same stack, e.g., PNPNP or NPNPN, each with its own gate, i.e., the side of a polysilicon gate layer. The SRAM cell may be radiation hardened by selectively thickening gate layers to increase storage node capacitance, providing high resistance cell wiring or by including a multi-layered gate oxide layer of NO or ONO, or by any combination thereof.

摘要: A pair of directly coupled Field Effect transistors (FETs), a latch of directly coupled FETS, a Static Random Access Memory (SRAM) cell including a latch of directly coupled FETs and the process of forming the directly coupled FET structure, latch and SRAM cell. The vertical FETs, which may be both PFETs, NFETs or one of each, are epi-grown NPN or PNP stacks separated by a gate oxide, SiO.sub.2. Each device's gate is the source or drain of the other device of the pair. The preferred embodiment latch includes two such pairs of directly coupled vertical FETs connected together to form cross coupled invertors. A pass gate layer is bonded to one surface of a layer of preferred embodiment latches to form an array of preferred embodiment SRAM cells. The SRAM cell may include one or two pass gates. The preferred embodiment SRAM process has three major steps. First, preferred embodiment latches are formed in an oxide layer on a silicon wafer. Second, the cell pass gates are formed on a pass gate or Input/Output (I/O) layer. Third, the I/O layer is bonded to and connected to the preferred latch layer.
