摘要： A microprocessor having a monolithically integrated environmental sensor is provided. The microprocessor is shielded from an environmental signal by isolation which is specific to the type of sensor used, thereby allowing the sensor to be exposed to the environmental signal. Optionally, high current drive circuitry is integrated with the microprocessor-sensor circuit to provide a monolithic device which allows control of power loads based in part on output from an environmental sensing device.

摘要： An accelerometer in which the seismic mass is formed in the shape of an annulus. The annular shape allows twisting motions as well as displacement of the seismic mass to be sensed and restoring electrostatic forces applied. This allows the supporting spring to be made extremely weak avoiding the mechanical limitations of springs.

摘要： In semiconductor memory cells of the type including flip flop circuits in each cell and two sense output lines for determining the binary bits stored in the cell, an attempt to read data stored in the cell after a previous operation, before the sense lines have been fully restored to their quiescent state can result in the loss of data. This invention provides a means for restoring the sense lines very rapidly after an operation so that loss of data is prevented and the memory may be accessed at a higher frequency.

摘要： An environmental sensor integrated with high current drive device is provided. An environmental sensor is fabricated on a semiconductor substrate using conventional MOS process used for N-well CMOS logic and DMOS power transistors. An N-well is preferably used as a junction etch stop for micromachining of mechanical sensor components. A high voltage P-type region is used to electrically isolate the high current device from the sensor device. By locating the sensor device away from the high current drive device on a common semiconductor substrate, good performance can be achieved from the sensor even while the high current device dissipates a large amount of power.
