    摘要: An anti-fuse structure that can be programmed at low voltage and current and which potentially consumes very little chip spaces and can be formed interstitially between elements spaced by a minimum lithographic feature size is formed on a composite substrate such as a silicon-on-insulator wafer by etching a contact through an insulator to a support semiconductor layer, preferably in combination with formation of a capacitor-like structure reaching to or into the support layer. The anti-fuse may be programmed either by the selected location of conductor formation and/or damaging a dielectric of the capacitor-like structure. An insulating collar is used to surround a portion of either the conductor or the capacitor-like structure to confine damage to the desired location. Heating effects voltage and noise due to programming currents are effectively isolated to the bulk silicon layer, permitting programming during normal operation of the device. Thus the potential for self-repair without interruption of operation is realized.

    摘要: A differential receiver for sensing small input voltage swings by using a built in reference voltage obtained by a difference in threshold voltage between a differential pair of closely spaced transistors. The difference in threshold voltage can be produced by different values of ion implantation of the gates of the transistor pair with the same material, or by dosages using different materials. The difference in threshold voltage can also be obtained by using different transistor channel lengths. The threshold voltages can also be modulated by the control of the transistor substrate voltages using a voltage control substrate means.

A data input line, or output line, or data input/output line is connected between the processor and the memory. A transmission line stub having a length that is incrementally variable is connected to the memory control input side of the control line 14. The impedance Z0 of the transmission line stub is equal to that of the control line and is open circuited at the end which results in voltage doubling to achieve high speed synchronization between control signals and data signals and to ensure valid data at high clock rates.

    摘要: A method and apparatus for using multi-level signals in a gain cell is shown. The method involves of first, storing a value of a multi-level signal in the gain cell. A stepping waveform is then applied to the gain cell and the gain cell outputs a conduction signal when the level of the stepping waveform corresponds to the value of the multilevel signal that is stored within the gain cell. Finally, the value of the multi-level signal is determined through the conduction signal and the corresponding level of the stepping waveform. The gain cell includes an input device, a storage device and a level comparator, which responds to the stepping waveform generated from a stepping signal generator and outputs the conduction signal for determining the value of the multi-level signal stored in the storage device.
