摘要： A CMOS buffer includes an input inverter, and a pull-up circuit coupled to the input inverter. The pull-up circuit provides an additional, temporary, signal pull-up on the output terminal of the input inverter during a high to low signal transition on its input terminal. The pull-up circuit includes a means for creating a signal delay. In one embodiment, the means for creating a signal delay includes a second and third inverter in series, the second inverter receiving an output signal from the input inverter. The pull-up circuit further includes two transistors for transferring a high signal to an output line of the input inverter. One transistor is controlled by a signal transferred by the means for creating a delay. The other transistor is controlled by an input signal to the input inverter. This pull-up circuit configuration ensures that the signal transition from low to high is substantially equal to the signal transition from high to low on the output line of the input inverter. The input inverter is then coupled to a driving circuit inverter to provide a CMOS buffer configuration.

摘要： A memory system having a single-sided memory cell, a first voltage supply terminal and a control circuit is provided. The single-sided memory cell has a first node and a second node. Data values are written to the memory cell by selectively applying data signals to the first node or the second node, and data values are read from the memory cell from the second node. The control circuit is coupled to receive a data signal having one of a first state and a second state. The control circuit couples the first node of the memory cell to the first voltage supply terminal when the data signal is in the first state, thereby writing a first data value to the memory cell. The control circuit couples the second node of the memory cell to the first voltage supply terminal when the data signal is in the second state, thereby writing a second data value to the memory cell. Because the first voltage supply terminal is used to write both the first and second data values to the memory cell, problems associated with inadequate write voltages are eliminated by appropriate selection of the first supply voltage.

摘要： Problems associated with excessive crowbar current due to input signal transitions at a buffered programmable interconnect point are solved by inserting a transistor switch between power and ground. The inserted switch is in series with the input buffer and is controlled by a memory cell which also controls the pass/no-pass state of the interconnect. An OFF inserted switch blocks current that flows during switching when the memory cell output causes a no-pass state of the interconnect.

摘要： Propagation delay along a signal path in a programmable logic device is reduced by providing improved switching and buffering along the device signal path. Such improvement is achieved by providing a separate buffer for each signal path leading from a given device input pad. In this manner, the buffer is smaller without increasing net power consumption. Improved output drivers are also provided in which device sizes are optimized to sink/source larger amounts of current, thereby improving device speed. A feedback arrangement, including a bootstrap device, provides a path that augments the current provided within the output buffer, thereby assisting a low to high signal transition. An improved OR gate is also provided that precharges a gate output line to ensure fast state transition, while eliminating the need for complementary gate switching logic.

摘要： Output circuits that provide compatibility with various input and output voltage levels without sacrificing performance. A pull-up on an output terminal is gated by an internal node, and the invention encompasses various circuits and means for placing a data input signal on this internal node. One embodiment includes a level shifter on the data input path, while also providing an alternative path through the output circuit that bypasses the level shifter. When the input data value goes high, the alternative path quickly places an attenuated high value on the internal node. The level shifter then becomes active and raises the voltage on the internal node to the output power high level, ensuring that the output pull-up is completely off.
