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： A self-referencing redundancy scheme in a content addressable memory may use a faulty bit table, populated during manufacturing, to indicate, not only the address of all the defective memory locations, but also the data which they should hold. Then, during read out, a read out state machine may access the faulty bit table, determine the data the faulty location should have held, and write that faulty data onto latches associated with the faulty memory elements.
