    摘要: A high-speed, low-power input buffer for an integrated circuit device in which the input voltage (VIN) is coupled to both a pull-up and a pull-down transistor. In accordance with a specific embodiment, the input buffer utilizes a reference voltage input (VREF) during a calibration phase of operation but not when in an active operational mode. A maximum level of through current is supplied when VIN=VREF with lower levels of through current at all other VIN voltages. In an integrated circuit device incorporating an input buffer as disclosed, two (or more) input buffers may be utilized per device input pin.

    摘要: A reduced area dynamic random access memory (DRAM) cell and method for fabricating the same wherein the cell occupies an area smaller than one photolithography pitch by two photolithography pitches through the formation of sidewall spacers along a first pattern to define a first portion of the active region of the memory cell and a second orthogonally oriented pattern to define a second portion of the active region of the memory cell thereby creating a ladder shaped active region for a column of the memory cells.

    摘要: A circuit provides the widest possible window for capturing data and preventing run-through in a FIFO register. The FIFO register includes two registers per I/O. Two FIFO input clocks are used, one for each FIFO register. When one FIFO clock is active, the other is automatically disabled. Initially, the circuit is reset such that one clock is active, and the other disabled. Upon receiving a valid READ command, a shift chain attached to the FICLK that is currently low begins counting the clock cycles. This eventually determines when the FICLK that is currently low can be enabled. The final enable is dependent upon the turning off the FICLK that is currently high. The FICLK that is enabled during the reset turns off a fixed delay after the falling edge of the YCLK associated with the READ command.
