    摘要: A computer system including a control logic and a storage coupled to the control logic. The storage includes a plurality of bitcells and bitlines used to transfer data between the control logic and the bitcells. The control logic provides an address of a target bitcell to the storage.

    摘要: A device for adaptively controlling a voltage supplied to circuitry in close proximity to the device, comprising a processing module and a first tracking element coupled to the processing module. The first tracking element produces a first value indicative of a first estimated speed associated with the circuitry. The device also comprises a second tracking element coupled to the processing module. The second tracking element produces a second value indicative of a second estimated speed associated with the circuitry. The processing module compares each of the first and second values to respective target values and causes a voltage output to be adjusted based on the comparisons. The first and second tracking elements comprise a plurality of transistors, at least some of the transistors selectively provided with a transistor bias voltage to adjust transistor speed.

    摘要: 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.

    摘要: A compact data line arrangement (600) includes “twisted” data line pairs (604a-604c) disposed in a first direction. Each twisted data line pair (604a-604c) includes an upper segment pair (608a-608f) that is connected to a lower segment pair (610a-610f) by a twist structure (612a-612c). The upper and lower segment pairs (608a-608f and 610a-610f) can be formed with a first pitch using phase-shifted lithography. The twist structures (612a-612c) are formed from a second conductive layer, and have a greater pitch than the first pitch. The twist structures (612a-612c) are generally arranged in a second direction that is perpendicular to the first direction. Selected twist structures (612b) are offset in the first direction with respect to adjacent twist structures (612a and 612c). The offset twist structures (612a-612c) allow supplemental conductive lines (618) to be formed from the first conductive layer that extend in the first direction, between adjacent offset twist structures (612a and 612b).

    摘要: A dynamic random access memory (DRAM) includes a Y-select circuit (218) that connects a pair of bit lines (204a and 204b) to a pair of sense nodes (210a and 210b). The Y-select circuit (218) provides a first impedance in a read operation, and a second impedance that is lower than the first impedance, in a write operation. Changes in Y-select circuit (218) impedance are achieved by driving transistors (N210a and N210b) within the Y-select circuit (218) with a first voltage during a read operation, and a second voltage during a write operation.
