摘要：
Described examples include sensing circuits and reference voltage generators for providing a reference voltage to a sensing circuit. The sensing circuits may sense a state of a memory cell, which may be a PCM memory cell. The sensing circuits may include a cascode transistor. Examples of reference voltage generators may include a global reference voltage generator coupled to multiple bank reference voltage generators which may reduce an output resistance of the voltage generator routing.
