摘要： A power-on reset (POR) circuit comprises a transistor connected ad diodes for setting temperature time delay coupled to a power supply voltage, a transistor switch, and buffering circuits. The trip point voltage of the POR circuit depends only on one type of transistor, such as the switching transistor so that the p-to-n skew variations do not affect the trip point. The switching transistor has a resistor connected from base to ground and another resistor connected to the power supply voltage to limit current flow during transitions.

摘要： A bit/column latch comprising a pair of first and second cross-coupled CMOS inverters. Each inverter of the pair comprises an NMOS transistor and a PMOS transistor. The first CMOS inverter has the source of its NMOS transistor coupled to ground via a control transistor and has its output connected to the associated bit line. When low voltage data intended for the associated memory cell appears on the bit line, the control transistor is barely turned on to weaken the NMOS transistor of the first inverter. This makes it easier for the data on the bit line to turn on the NMOS transistor of the second inverter so as to switch the bit latch from storing a ‘low’ to storing a ‘high’. In other words, the data bit from the bit line is loaded into the bit latch. After that, the control transistor is strongly turned on and therefore it becomes transparent to the latch. As a result, the latch is stable when the bit line later ramps up to a high programming level.

摘要： A voltage regulator circuit that receives an input signal and provides an output signal that is clamped at a specified voltage desired for an internal circuit. The disclosed voltage regulator circuit includes a plurality of subcircuits including a voltage tracking subcircuit in which the output voltage tracks the input voltage with no voltage drop when the input voltage starts to rise from zero volts. If the input voltage increases to a desired voltage level for the internal circuit, the voltage tracking subcircuit clamps the output voltage to remain at that voltage. If the input voltage further increases to a higher voltage, the voltage tracking subcircuit is disabled and one of a plurality of voltage maintaining subcircuit takes control so that the output voltage remains at the desired voltage for the internal circuit.

摘要： A driver circuit for use in an array of picture elements in a liquid crystal display is capable of displaying one set of image data while receiving a second set of image data. A first select switch transistor responsive to a first select signal controls the coupling of a first image to a first storage capacitor. A second select switch transistor responsive to a second select signal controls the coupling of a second image to a second storage capacitor. The first storage capacitor may be selectively coupled to an output node by means of a first enable switch transistor responsive to a first enable signal. The second storage capacitor may be selectively coupled to the same output node by means of a second enable switch transistor responsive to a second enable signal. By proper manipulation of the switch transistors, one storage capacitor may be coupled to the output node while the other storage capacitor is isolated from the output node and receiving new image data.

摘要： A fuse circuit includes a fusible element and a feedback path which causes the circuit to behave as if the fusible element is fully blown even though the fusible element in fact is partially intact. While a partially intact fuse normally would result in a continuous drain of power, the feedback path cuts off the current flow through the partially intact fusible element.

摘要： A power-on-reset circuit includes a first charging stage for building up a charge during power up. The rising voltage of the first charging stage is sensed and used to control means for charging up a second charging stage. When the second charging stage reaches a first voltage level, a circuit is tripped to pull the potential of the first to ground. The grounding of the first charging stage is fed back to the charging means which shuts off its power burning components and maintains the first voltage level at the second charging stage.

摘要： A sense amplifier for use in a serial configuration memory includes multiple stages which are enabled and disabled in a controller manner, in response to a control pulse. The control pulse is produced every Nth period of an externally provided clock signal, the clock being used to clock out a bitstream representing the contents of the memory device. In a preferred embodiment, N such sense amps are utilized to read out in parallel fashion the N memory cells (bits) that constitute an accessed memory location. The sense amps are therefore active only of a period of time sufficient to read out a memory cell.

摘要： A serial configuration memory device comprises an architecture wherein the reading out of data and the outputting of the bitstream are performed in pipeline fashion. As a result, the device is capable of outputting a bitstream based solely on the frequency of an externally provided clock, and is not limited by the slower operating speed of the sense amp circuitry. A caching scheme is provided which allows the first byte to be pre-loaded during a reset cycle so that the device can immediately begin outputting the bitstream as soon as the reset cycle completes. In a preferred embodiment of the invention, the bitstream consists of serially accessed memory locations starting from memory location zero. In one variation, the bitstream can begin from a memory location other than memory location zero.
