Coarse / fine programming of non-volatile memory is provided in which memory cells are programmed at a first rate of programming prior to reaching a coarse verify level for their intended state and a second rate of programming after reaching the coarse verify level but before reaching the final verify level for their intended state. Large sub-threshold swing factors associated with smaller memory cells can affect the accuracy of sense operations, particularly when sensing at a fine verify level after sensing at a coarse verify level without pre-charging the bit line between the different sensings. Different reference potentials are utilized when sensing at a coarse verify level and a final verify level. The different between the reference potentials can compensate for any discharge of the bit line during the coarse level sensing.

A drug delivery device such as an oral dosage form (ODF) with a toxic or potent core encapsulated by a non-toxic region. The non-toxic region may be a region including multiple layers, coatings, shells, and combinations thereof, which provides protection to and isolation from the toxic or potent core. The drug in the toxic or potent core is incorporated into the dosage form via, for example, three-dimensional printing, as a solution, solubilization or suspension of solid particles in liquid, rather than by the more conventional handling and compressing of dry powder. This minimizes the likelihood of creating airborne particles of the toxic drug during manufacturing, hence controlling and minimizing the exposure of manufacturing personnel to the hazardous substance. Wet dispensing of the toxic or potent drug further provides greater bioavailability of the drug to the patient.

An I / O circuit for measuring temperatures uses multiple cold-junction compensation sensors permanently affixed near the terminals of the terminal block in order to compensate significant temperature variation across the terminals of the I / O module (up to 3° C.) that can substantially affect the accuracy of thermocouple measurements.

In one embodiment, a third temperature sensor with relatively higher accuracy is used to compensate for lower accuracy of permanently affixed sensors.
