摘要： Systems and methods for controlling electro-migration, and reducing the deleterious effects thereof, are disclosed. Embodiments provide for reversal of an applied voltage to an integrated circuit when a measurement indicative of an extent of electro-migration indicates that a healing cycle of operation is warranted. During the healing cycle, circuits of the integrated circuit function normally, but electro-migration effects are reversed. In one embodiment, micro-electro-mechanical switches are provided at a lowest level of metallization to switch the direction of current through the levels of metallization of the integrated circuit. In another embodiment, if the measurement indicative of the extent of electro-migration exceeds a reference level by a specifiable amount, then the voltage applied to the integrated circuit is reversed in polarity to cause current to switch directions to counter electro-migration. A plurality of switches are provided to switch current directions through a lowest level of metallization so that the circuits function normally even though the polarity of the applied voltage has been reversed.

摘要： A method and apparatus are provided for implementing an enhanced hand shake protocol for microelectronic communication systems. A transmitter and a receiver is coupled together by a transmission link. The transmitter receives an idle input. The idle input is activated when the transmitter is not transmitting data and the transmitter applies a first common mode level to the receiving unit. The idle input is deactivated when the transmitter is ready to transmit data and the transmitter raises the common mode level to the receiving unit. Responsive to the receiver detecting the common mode level up-movement, then the receiver receives the transmitted data signals. After the desired data has been sent, the transmitter terminates communications, drops the common mode level with the idle input being activated.

摘要： An apparatus and method is provided for detecting loss of differential signal carried by a pair of differential signal lines. According to the method, a common mode level is detected from voltages on the pair of differential signal lines. A threshold level is generated, referenced to the detected common mode level. A signal level is generated from the voltages on the pair of differential signal lines, the signal level being averaged over a first period of time. From the threshold level and the detected common mode level a reference level is generated, the reference level being averaged over a second period of time longer than then the first period of time. The signal level is compared to the reference level to determine if a signal is present on the pair of differential signal lines.
