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 electromechanical switch device includes a first switch portion, a second switch portion and an actuator device. The actuator device is configured to provide an actuation force, thereby actuating the first and second switch portion relative to each other to change from a disconnected to a connected state. The actuator device is further configured to provide the actuation force with a modulation at least when the first and second switch portion are in the connected state. A method of operating an electromechanical switch device is also provided.

摘要： A pattern matching accelerator (PMA) for assisting software threads to find the presence and location of strings in an input data stream that match a given pattern. The patterns are defined using regular expressions that are compiled into a data structure comprised of rules subsequently processed by the PMA. The patterns to be searched in the input stream are defined by the user as a set of regular expressions. The patterns to be searched are grouped in pattern context sets. The sets of regular expressions which define the pattern context sets are compiled to generate a rules structure used by the PMA hardware. The rules are compiled before search run time and stored in main memory, in rule cache memory within the PMA or a combination thereof. For each input character, the PMA executes the search and returns the search results.
