摘要： The problem of the distributed voltage drop along a resistive word line through which fusible elements of a circuit array are selectively programmed to a state of high resistance (effective open circuit) is circumvented by incorporated an auxiliary word line driver as part of the array. The auxiliary word line driver is coupled to the word line at a location apart from the main word line driver, so as to reduce the effective resistance and consequential voltage drop along the word line. As a result, for each memory cell along a respective word line there is sufficient "rupturing current" capability, whereby each fusible element of the memory array may be successfully programmed regardless of its physical location within the array.

摘要： A testing circuit for testing fuse elements in programmable memory devices. The circuit provides for testing whether the fuses have the proper resistance, both after manufacturing and after programming of the memory device. The testing circuit includes a current varying means which may include either a variable resistance or a variable current sink. The variable resistance is connected to a fuse element to form a voltage divider with the same. A sensing amplifier is connected at a node therebetween for sensing the current through the fuse element and, thus, the resistance of the same. The variable current sink provides variable current levels, thereby achieving the same above results.

摘要： System and method for substantially reducing an involvement of an applications processor in receiving data from a touchscreen display. In one aspect, the system includes a controller may be configured in an autonomous mode where it automatically measures the touchscreen display based configuration information received from the applications processor, determines notable events based on the measurement data, stores data and event identifiers related to the notable events in a memory, and sends a notification to the applications processor when event data is available In another aspect, the system includes a controller that filters user interactions events and transmits data related to only notable events to the applications processor. Because of the autonomous and event filtering operations of the touchscreen controller, there are substantially less communications between the controller and the applications processor. This improves the speed and efficiency of the applications processor.

摘要： A keeper switch circuit is configured to minimize capacitive coupling between the gate and drain of a cascode transistor. The keeper switch circuit is coupled between the source and gate of a cascode transistor. The keeper switch circuit is on if a voltage at the drain of the keeper switch circuit corresponds to a first logic level. The source and gate of the cascode transistor are coupled together if the keeper switch circuit is on.

摘要： A two-input, two-output multiplexer circuit has two tri-state inverter circuits and two switch circuits. The multiplexer outputs may be interchanged depending on a control signal. Each tri-state inverter circuit is configured to receive one of the inputs, invert it, and provide the corresponding inverted signal at the corresponding multiplexer output when the control signal corresponds to a first logic level. If the control signal corresponds to a second logic level: each switch circuit is configured to turn on, and each tri-state inverter circuit is configured to provide a high-impedance output. The first switch circuit is configured to couple the first inverted signal to the second multiplexer output when the first switch circuit is on. Similarly, the second switch circuit is configured to couple the second inverted signal to the first multiplexer output when the second switch circuit is on.

摘要： A method and apparatus are disclosed for providing programmable hysteresis to a differential comparator. Programmable hysteresis is accomplished by adding voltage followers to the input stage and a current steering network to the output stage of the comparator such that DC bias currents flowing in the current steering network are mirrored via current mirrors so as to flow through the voltage followers at the input stage. By adding a desired offset current to one of the two input voltage follower DC bias currents in dependence on the output state of the comparator in such a manner as to provide positive feedback, an offset voltage is generated due to the unequal voltage drops of the voltage followers resulting in hysteresis which can be controlled in real-time.

摘要： A test enabling circuit for actuating specific testing circuitry contained within a programmable device, whereby the test enabling circuit and a portion of the normal operational circuits of the device share a common input pin. Because of the dual functionality of the common input pin, the test enabling circuit is designed to respond to a specified test signal, which is either of an opposing polarity, or of a higher magnitude of the same polarity with respect to the normal operational signal. The enabling circuit includes several IGFET devices arranged such that the noise margin of the enabling circuit may be adapted for accommodating varying environments of noise. ESD circuitry is included to protect the testing and test enabling circuits against electrostatic discharge.
