  • Patent number: 6831337
    Abstract: A method of forming a transistor (70) in a semiconductor active area (78). The method forms a gate structure (G2) in a fixed relationship to the semiconductor active area thereby defining a first source/drain region (R1) adjacent a first gate structure sidewall and a second source/drain region (R2) adjacent a second sidewall gate structure. The method also forms a lightly doped diffused region (801) formed in the first source/drain region and extending under the gate structure, wherein the lightly doped diffused region comprises a varying resistance in a direction parallel to the gate structure.

  • Patent number: 6828161
    Abstract: The present invention is directed to a method of forming an FeRAM integrated circuit, which includes forming a multi-layer hard mask. The multi-layer hard mask comprises a hard masking layer overlying an etch stop layer. The etch stop layer is substantially more selective than the overlying masking layer with respect to an etch employed to remove the bottom electrode diffusion barrier layer. Therefore during an etch of the capacitor stack, an etch of the bottom electrode diffusion barrier layer results in a substantially complete removal of the hard masking layer. However, due to the substantial selectivity (e.g., 10:1 or more) of the etch stop layer with respect to the overlying masking layer, the etch stop layer completely protects the underlying top electrode, thereby preventing exposure thereof.

  • Patent number: 6829007
    Abstract: An image processing apparatus (800) for a charge coupled device having hot/cold pixel and line noise filtering is disclosed which provides optical black and offset correction. The present invention teaches an offset and optical black correction circuit having a digital filter to obtain noise-free optical black correction for charge-coupled devices such that a digitally programmable bandwidth exists. The sum of the channel offset and optical black level is averaged for a given number of lines having a number of optical black cells per line and this sum passes through a digital filter. Moreover, the channel is digitally calibrated to obtain a user programmed ADC (810) output which corresponds to that average.

  • Patent number: 6828513
    Abstract: A connector pad includes projections extending radially outwardly from an inner portion of the pad to help stabilize and reinforce the pad. The added stability allows the radial thickness of an inner portion of the pad to be reduced. This decreases the surface area of the pad and reduces the opportunity for capacitive build up to occur relative to an associated conductive plane in a circuit board.

  • Patent number: 6829669
    Abstract: A bus bridge is defined to provide an interface between two AHB buses. These busses normally have separate requirements but both must provide high performance. The first is for transfer of data from CPU to memory and peripherals. The second is to support the transfer of a large amount of data by a single peripheral to local memory or other local peripherals. The AHB-to-HTB bus bridge provides a means for the interfacing these two separate AHB buses allowing communication between them and securing data integrity. The bus bridge of this invention is defined to be an AHB memory bus slave but a high performance data transfer bus master.

  • Patent number: 6829696
    Abstract: A data processing system (e.g., microprocessor 30) for packing register data while storing it to memory and unpacking data read from memory while loading it into registers using single processor instructions. The system comprises a memory (42) and a central processing unit core (44) with at least one register file (76). The core is responsive to a load instruction (e.g., LDW_BH[U] instruction 184) to retrieve at least one data word from memory and parse the data word over selected parts of at least two data registers in the register file. The core is responsive to a store instruction (e.g., STBH_W instruction 198) to concatenate data from selected parts of at least two data registers into at least one data word and save the data word to memory. The number of data registers is greater than the number of data words parsed into or concatenated from the data registers. Both memory storage space and central processor unit resources are utilized efficiently when working with packed data.

  • Patent number: 6828825
    Abstract: Systems and methods are provided for detecting a state change of a level shifter and actively driving the level shifter into the new state to facilitate the recovery of the level shifter. The system and method also provide logic for setting up the level shifter for the next transition. A transition of a high logic to low logic of a first internal node and a second internal node is monitored. The first internal node and the second internal node transition between opposing logic levels, such that one internal node is pulled low and the other internal node is pulled high. The monitor determines when one node is pulled low and actively drives the other node to a logic high to facilitate the recovery of the level shifter.
