Abstract
The present invention pertains to a circuit arrangement that, in one example, facilitates reading or determining an amount of current that flows through a memory cell when one or more voltages are applied to the cell. The amount of current resulting from the applied voltages is a function of the amount of charge stored within the cell, among other things, and the amount of stored charge represents information stored within the cell. As such, reading the resulting current allows data stored within the cell to be accessed and retrieved. It will be appreciated however, that use of the circuitry disclosed herein is not limited to memory applications. Rather, it can be used in any application where current sensing is required along with a regulated supply voltage.
