    Abstract: A device for directly loading data onto bit lines of DRAMs. The device eliminates the need for performing a read cycle prior to a write cycle by bypassing the sense amplifiers of the DRAM. An I/O data line is connected to a bit line by a first transmission gate. A second transmission gate is electrically connected between the first transmission gate and the sense amplifier. A voltage level representing a data bit is loaded directly onto a bit line by turning off the second transmission gate to isolate the sense amplifier from the bit line and turning on the first transmission gate to connect the data line to the bit line. The voltage level on the bit line is then stored in a memory cell connected to the bit line.

    Abstract: A method and circuit for testing a packaged semiconductor memory device allow the acquisition of information on redundant elements by performing one of three possible redundancy rollcall tests on the packaged memory chip. By stimulating the packaged device's pins, the memory chip is set in one of the three test modes. In the first test mode, a preset signal indicating redundancy is sensed and the state of an output pin is changed. In the second test mode, memory array rows are sequentially addressed and the state of an output pin is changed when a redundant row is addressed. In the third test, array columns are sequentially addressed and, when a redundant column is addressed, the state of the output pin to which the redundant column is mapped is changed.

    Abstract: Silver interconnects are formed by etching deep grooves into an insulating layer over the contact regions, exposing portions of the contact regions and defining the interconnects. The grooves are etched with a truncated V- or U-shape, wider at the top than at any other vertical location, and have a minimum width of 0.25 .mu.m or less. An optional adhesion layer and a barrier layer are sputtered onto surfaces of the groove, including the sidewalls, followed by sputter deposition of a seed layer. Where aluminum is employed as the seed layer, a zincating process may then be optionally employed to promote adhesion of silver to the seed layer. The groove is then filled with silver by plating in a silver solution, or with silver and copper by plating in a copper solution followed by plating in a silver solution. The filled groove which results does not exhibit voids ordinarily resulting from sputter deposition of metal into such narrow, deep grooves, although seams may be intermittently present in portions of the filled groove where metal plated from the opposing sidewalls did not fuse flawlessly at the point of convergence. Portions of the silver and other layers above the insulating material are then removed by chemical-mechanical polishing, leaving a silver interconnect connected to the exposed portion of the contact region; and extending over adjacent insulating regions to another contact region or a bond pad. Silver interconnects thus formed may have smaller cross-sections, and thus a greater density in a given area, than conventional metallic interconnects.

    Abstract: A method and integrated circuit for providing drive signals to a polyphase dc motor. The integrated circuit is fabricated on a semiconductor substrate for providing drive signals to a polyphase dc motor. The circuit includes a coil drive circuit for connection to drive coils of the motor to selectively supply drive currents thereto in a predetermined sequence. A sequencer circuit commutatively selects the drive coils to which the drive currents are selectively supplied, and a motor, speed controlling circuit controls the speed of the motor by controlling the speed of commutation. A temperature sensing element, such as a diode, is fabricated in the substrate to indicate the temperature of the substrate, and a temperature measuring circuit is connected to the temperature sensing element and to the motor speed controlling circuit to operate the motor speed controlling circuit to slow the speed of the motor when the temperature of the substrate exceeds a first predetermined temperature. If desired, temperature measuring circuit can include a circuit for measuring a second temperature higher than the first predetermined temperature to operate a shut down circuit to turn off the motor if the substrate temperature is too high.

    Abstract: A power MOSFET suitable for use in RF applications and a method for making the same is disclosed. The power MOSFET reduces the gate coverage of the drain region of the device in order to decrease the device gate to drain capacitance C.sub.gd. A significant portion of the gate overlaying the drain region is eliminated by the removal of a portion of a polysilicon layer that is disposed over a substantial portion of the drain region that resides between the channel portions of the body regions of the device. The resulting open area, that is subsequently covered by an oxide layer, separates the polysilicon gate electrodes of the device. Finally, a metal layer is deposited over the entire structure to form the gate and source electrodes of the device.

    Abstract: A memory, such as a static random access memory (SRAM), includes at least one memory cell. The bit lines for that memory cell are selectively connected to corresponding write bit lines through a column select pass transistor and a selectively blowable fuse. A reset circuit is connected to the same write bit lines through a fuse structure mimic circuit. Responsive to data transitions on the write bit lines, the reset circuit operates to detect the occurrence of a memory operation to the memory cell and generate a reset signal for resetting the memory in preparation for a next write operation. To support substantially simultaneous presentation of write data to both the reset circuit and the memory cell, the fuse structure mimic circuit delays presentation of the write bit line data to the reset circuit. This introduced delay substantially corresponds to a delay in the presentation of the write bit line data to the memory cell resulting from driving the memory cell bit lines through the selectively blowable fuses.
