摘要： Apparatus and method for measuring the state of a resistive memory cell. A bias voltage controller applies a bias voltage to the cell and controls the level of the bias voltage. A feedback signal generator senses cell current due to the bias voltage and generates a feedback signal (SFB) dependent on the difference between the cell current and a predetermined target current. The bias voltage controller controls the bias voltage level in dependence on the feedback signal (SFB) such that the cell current converges on the target current. An output is provided indicative of the bias voltage level at which the cell current corresponds to the target current, thus providing a voltage-based metric for cell-state.

摘要： An approach to determine cantilever movement is presented. An observer based state estimation and statistical signal detection and estimation techniques are applied to Atomic Force Microscopes. A first mode approximation model of the cantilever is considered and an observer is designed to estimate the dynamic states. The cantilever-sample interaction is modeled as an impulsive force applied to the cantilever in order to detect the presence of sample. A generalized likelihood ratio test is performed to obtain the decision rule and the maximum likelihood estimation of the unknown arrival time of the sample profile and unknown magnitude of it. The use of the transient data results in sample detection at least ten times faster than using the steady state characteristics.
