摘要: Apparatus and methods for evaluating leakage currents of capacitances are described. Capacitances having excessive leakage currents may be disabled from use. An example apparatus includes a leakage detection circuit configured to be coupled to a capacitance block. The leakage detection circuit is configured to determine whether a leakage current of a capacitance of the capacitance block exceeds a current limit and is further configured to provide an output indicative of a status of the capacitance. A detection controller is coupled to the leakage detection circuit and a register, and the detection controller is configured to store data in the register indicative of the status of the capacitance based at least in part on the signal from the leakage detection circuit.

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.
