摘要： A system is disclosed for reducing or removing a form of read disturb in a non-volatile storage device. One embodiment seeks to prevent read disturb by eliminating or minimizing boosting of the channel of the memory elements. For example, one implementation prevents or reduces boosting of the source side of the NAND string channel during a read process. Because the source side of the NAND string channel is not boosted, at least one form of read disturb is minimized or does not occur.

摘要： The maximum allowable number of voltage programming pulses to program memory elements of a non-volatile memory device is adjusted to account for changes in the memory elements which occur over time. Programming pulses are applied until the threshold voltage of one or more memory elements reaches a certain verify level, after which a defined maximum number of additional pulses may be applied to other memory elements to allow them to also reach associated target threshold voltage levels. The technique enforces a maximum allowable number of programming pulses that can change over time as the memory is cycled.

摘要： A charge balancing modulation system for digitizing the output of a variable impedance sensor utilizes synchronous excitation of the input sensor and AC coupling of the analog input signal. In one embodiment, the modulation system includes a switched excitation source for exciting the input sensor and generating an input voltage step in response, and an integrator including an input capacitor, an amplifier and an accumulation capacitor. The input capacitor AC couples the input voltage step to the integrator to form an input charge. A reference charge packet is generated in a data dependent manner and coupled to the integrator simultaneously with the input charge. The integrator integrates charge associated with the sum of the input charge and the reference charge, when applied. The modulation system generates an output data stream exhibiting a ones density proportional to the magnitude of the average input voltage step.

摘要： A digitizing temperature measurement system for providing a digital temperature measurement includes an excitation source for providing switched excitation currents to two or three temperature sensing elements and an ADC circuit including a charge-balancing modulator and a digital post processing circuit. The system utilizes synchronous AC excitation of the temperature sensing elements and an AC coupled analog-to-digital converter input. The temperature measurement system also implements correlated double sampling for noise cancellation to provide low noise and highly accurate analog-to-digital conversions. The modulator receives a charge domain reference signal generated by a reference charge packet generator incorporating a charge based bandgap subsystem. Therefore, the temperature measurement system can be operated at very low supply voltages, such as 1.0 Vdc. A low noise and highly accurate temperature measurement system is thus realized where temperature measurements of very high resolutions (up to 16 bit) can be attained.

摘要： A digitizing ohmmeter system for providing a digital resistance measurement includes a current source for providing an excitation current to an impedance-varying input sensor and an ADC circuit including a charge-balancing modulator and a digital post processing circuit. The system utilizes synchronous AC excitation of the input sensor and an AC coupled analog-to-digital converter input. The digitizing ohmmeter system also implements correlated double sampling for noise cancellation to provide low noise and highly accurate analog-to-digital conversions. The ADC circuit includes a reference signal generator generating a resistance reference signal by time-sharing the excitation current with the input sensor. The digitizing ohmmeter system thereby realizes fully ratiometric operation such that neither a precise current source nor a precise voltage source is required for accurate resistance measurements.

摘要： A current source includes a first circuit branch of a pair of diode-connected transistors with a resistor connected at the drain terminal and a second circuit branch of an inverter pair of transistors. Both of the circuit branches are supplied by a first current source powered by a supply voltage. The transistors are biased in the subthreshold region and have non-nominal size ratios. A first voltage and a second voltage are established across the resistor and the voltage difference causes a current proportional to absolute temperature to flow in the resistor. The second circuit branch functions as an error amplifier providing an “error signal” to facilitate voltage regulation. The regulation is realized in a third circuit branch which receives the “error signal” and draws excess current from the first current source so that the first voltage and the second voltage remain at the ideal regulated operation point.
