Method of writing to a spin torque magnetic random access memory

A spin-torque magnetoresistive memory includes array read circuits and array write circuits coupled to an array of magnetic bits. The array read circuits sample magnetic bits in the array, apply a write current pulse to the magnetic bits to set them to a first logic state, resample the magnetic bits, and comparing the results of sampling and resampling to determine the bit state for each magnetic bit.

Differential current measurements to determine ion current in the presence of leakage current

An ion chamber provides a current representative of its characteristics as affected by external conditions, e.g., clean air or smoke. A direct current (dc) voltage is applied to the ion chamber at a first polarity and the resulting current through the ion chamber and parasitic leakage current is measured at the first polarity, then the dc voltage is applied to the ion chamber at a second polarity opposite the first polarity, and the resulting current through the ion chamber and parasitic leakage current is measured at the second polarity.
