摘要： A Flash memory system and a method for data management using the system's sensitivity to charge-disturbing operations and the history of charge-disturbing operations executed by the system are described. In an embodiment of the invention, the sensitivity to charge-disturbing operations is embodied in a disturb-strength matrix in which selected operations have an associated numerical value that is an estimate of the relative strength of that operation to cause disturbances in charge that result in data errors. The disturb-strength matrix can also include the direction of the error which indicates either a gain or loss of charge. The disturb-strength matrix can be determined by the device conducting a self-test in which charge-disturb errors are provoked by executing a selected operation until a detectable error occurs. In alternative embodiments the disturb-strength matrix is determined by testing selected units from a homogeneous population.

摘要： A Flash memory system and a method for data management using the embodiments of the invention use special test cells with Early Degradation Detection (EDD) circuitry instead of using the actual user-data storage cells are described. The Flash memory test cells can be made to serve as a “canary in a coal mine” by being made more sensitive than the standard cells by using experimentally determined sensitive write VT and variable read VT. Techniques for early degradation detection (EDD) in Flash memories measure the dispersion of the threshold voltages (VT's), of a set (e.g. page) of NAND Flash memory cells during read operations. In an embodiment of the invention the time-to-completion (TTC) values for the read operation for the memory cells are used as a proxy for dispersion of the threshold voltages (VT's). A Dispersion Analyzer determines the dispersion of the set of TTC values.

摘要： In a method of head-disk contact detection in a hard disk drive, a Radio Frequency (RF) carrier signal is injected into a slider which is flying above a surface of a disk in a hard disk drive. A modulated version of the RF carrier signal is received from the slider. The modulated version of the RF carrier signal is demodulated to achieve a demodulated signal. A signal spectrum of a range of frequencies in the demodulated signal is monitored for activity indicative of a contact between a head of the slider and the surface of the disk. An occurrence of the contact is determined based upon an occurrence of the activity.

摘要： An amplification system for reducing DC offset in an input signal uses a low pass filter to isolate a DC component of the input signal. The system then subtracts the DC component from the input signal. In one embodiment, the system includes first and second amplifiers in addition to the low pass filter. The first amplifier amplifies the input signal to generate a first amplified signal at a differential output port of the amplification system. The second amplifier amplifies a low pass filtered version of the input signal to generate a second amplified signal at the differential output port of the amplification system. The outputs of the first and second amplifiers are connected to the differential output port of the amplification system in such a way that the first and second signals combine 180 degrees out of phase at the output port. An automatic gain control circuit is also provided that automatically adjusts the gain of the amplification system without changing a bias level associated with the first and second amplifiers.

摘要： An ultra wide band (UWB) low noise amplifier (LNA) includes a common-gate (CG) amplifying element in cascode with a common-source (CS) amplifying element, and a load-tracking (LT) network to, at least in part, track a changing output impedance of the cascode helping to provide a substantially constant gain over an ultra wide frequency band of interest. The LT network may include of a parallel combination of a capacitive element, an inductive element, and a resistive element, which may be selected to, at least in part, track the changing output impedance of the cascode over an ultra wide frequency band. An initial common-gate stage may compensate for a capacitive input impedance of the cascode and may provide a substantially matched antenna input over the ultra wide frequency band. The amplifier may also include one or more resistor-based amplifying stages after the cascode.
