| 20110051508 | MULTILEVEL PROGRAMMING OF PHASE CHANGE MEMORY - A method and device for performing a program operation of a phase change memory (PCM) cell. The method includes the steps of applying one or more programming pulses according to a predefined programming scheme to achieve a target resistance level of the PCM cell, wherein the programming scheme is operable to perform in a first programming mode one or more annealing steps to approach the target resistance, wherein the programming scheme is operable to perform in a second programming mode one or more melting steps, wherein the programming scheme is operable to start in the first programming mode and to switch to the second programming mode if the target resistance level of the PCM cell has been undershot in the first programming mode. | 03-03-2011 |
| 20110069539 | PROGRAMMING MULTI-LEVEL PHASE CHANGE MEMORY CELLS - A method and a feedback controller for programming at least one multi-level phase-change memory cell with a programming signal. The method and feedback controller include a sequence of write pulses applied to the multi-level phase change memory cell, wherein the feedback controller adjusts in real time at least one parameter of each write pulse as a function of a determined resistance error of the phase-change memory cell with respect to a desired reference resistance level. | 03-24-2011 |

| 20090080107 | METHOD OF CONTROLLING MOVEMENTS OF A POSITION OF A MICROSCANNER - The invention relates to a method of controlling movements of a positioner of a micro-scanner, the method comprising: determining the vibration resonance frequency ranges of the positioner, and performing a main scan by a controlled movement of the positioner. | 03-26-2009 |
| 20090319866 | ERASURE FLAGGING SYSTEM AND METHOD FOR ERRORS-AND-ERASURES DECODING IN STORAGE DEVICES - A system and method for erasure flagging for errors-and-erasures decoding in storage devices includes determining a deviation measure between a read/write head position relative to a track of symbols in storage media. A reliability value is determined for the symbols based on the deviation measure. Flagging the symbols with a reliability value below a threshold as erasures is performed. The symbols are decoded using errors-and-erasures decoding in an iterative procedure. | 12-24-2009 |
| 20100085056 | MAGNETO-RESISTANCE BASED TOPOGRAPHY SENSING - A topography sensor and method include a probe configured to traverse a surface to determine a topography. A stray magnetic field is disposed in proximity to the probe. A magneto-resistive sensor is configured so that the stray magnetic field passing through it changes in accordance with positional changes of the probe as the probe tip traverses the surface. | 04-08-2010 |
| 20100201289 | HIGH-SPEED ELECTROSTATIC ACTUATION OF MEMS-BASED DEVICES - A micro-electro mechanical device includes a first structure, a second structure offset from the first structure by a gap.
