Abstract: Systems and methods for detecting the mode (a.k.a., state) of a fuse or set of fuses in a device such as an integrated circuit. One embodiment comprises a method for determining three fuse states (uncut, cut, and destroyed) by comparing the fuse voltage with two reference voltages. Each fuse state has a different (indicative) impedance and is associated with a fuse voltage. The fuse voltage is below, between, or above two reference voltages, thereby determining the fuse state. One embodiment includes the fuse in series with a read transistor as well as two reference voltage generators, each comprising a resistor and a transistor (equivalent to the read transistor). Both resistors' impedances are greater than the uncut fuse impedance and one is less than the cut fuse impedance. Two comparators are used to bracket the fuse voltage, indicating that the fuse is uncut, cut, or destroyed.

Abstract: Systems and methods for conveying signals between integrated circuit (IC) components in domains having different supply voltages. AC coupling is used to increase the speed at which the common mode voltage of a signal is shifted from one level to another. One embodiment comprises a method for level shifting a binary signal in an IC. This method includes receiving an input binary signal and decoupling its AC component from its common mode component. A second common mode component is added to the AC component, providing a binary output signal. The common mode voltage of the input signal may be greater (or smaller) than that of the output signal. In one embodiment of the method, duty cycle compensation (DCC) is performed. The DCC drives the duty cycle toward a desired value.

Abstract: Systems and methods for increasing the frequency range of an output signal generated by a VCO, where one or more variable delay units are incorporated into an interpolative VCO to decrease the minimum frequency at which the VCO oscillates. In one embodiment, the VCO includes a ring of serially connected inverters, a set of bypass circuits and a set of variable delay units. The bypass circuits are coupled to the ring of serially connected inverters to bypass one or more of the serially connected inverters when enabled. Each variable delay unit delays signal transitions at the input of a corresponding one of the serially connected inverters by a variable amount. The variable delay units may be positioned in series with the ring of inverters, in parallel with the bypass paths, or in parallel with corresponding inverters in the ring of inverters.

Abstract: Systems and methods for controlling the programming current directed through a fuse or set of fuses in a device such as an integrated circuit. One embodiment comprises a method for applying different currents to a set of calibration fuses, identifying which currents cut the corresponding fuses without destroying them, and selecting one of the identified currents to use in programming one or more target fuses. In one embodiment, fuses that are cut but not destroyed are identified by passing the same read current through each of the calibration fuses and comparing resulting voltages to reference voltages which correspond to impedances between the impedances of the possible fuse states (uncut, cut and destroyed.) Fuse voltages between the reference voltages identify fuses which are cut but not destroyed.

Abstract: Provided is a method of manufacturing a magnetic head with which bonding of a slider and a suspension can be performed by taking an ABS pattern, which determines flying characteristics, as a reference, with no special fabrication required on the slider or the suspension. The method relates to a method of manufacturing a magnetic head for attaching a slider, on which an air bearing surface (ABS) is formed, to a suspension. A surface of the slider on which the ABS is formed is photographed, and the ABS and an engraved region formed within the ABS are identified from the photographed image. Then, a reference that serves as a guide in attaching the suspension is computed, and the slider is attached to the suspension based on the reference. It thus becomes possible for positive pressure and negative pressure that occur in the ABS to be well balanced centered about the suspension, making it possible to stabilize flying attitude and electrical characteristics.

Abstract: A regeneration controller for preventing particulate matter from increasing when an exhaust purification apparatus is inactivated. The regeneration controller includes an ECU 70 for heating the exhaust purification apparatus and eliminating the particulate matter accumulated in the exhaust purification apparatus when an estimated accumulation amount is greater than a reference accumulation amount. The ECU 70 obtains the estimated accumulation amount by estimating the amount of particulate matter accumulated in the exhaust purification apparatus. An exhaust temperature sensor 44 detects the temperature of the exhaust purification apparatus. The ECU 70 intermittently decreases the air-fuel ratio of exhaust to heat the exhaust purification apparatus and perform burn-up heating for burning the particulate matter. The ECU 70 further prohibits burn-up heating when the temperature detected by an exhaust temperature sensor 44 decreases to a catalyst inactivation level.
