摘要： A memory loopback system and method including an address/command transmit source configured to transmit a command and associated address through an address/command path. A transmit data source is configured to transmit write data associated with the command through a write path. Test control logic is configured to generate gaps between successive commands. A loopback connection is configured to route the write data from the write path to a read path. A data comparator is configured to compare the data received via the read path to a receive data source and generate a data loopback status output. Pattern generation logic can be configured to generate a loopback strobe, the loopback strobe being coupled to the read path. The pattern generation logic may be configured to synthesize a read strobe based on the test control logic and to use the synthesized read strobe as the loopback strobe. The loopback connection may be configured to route the address/command data from the address/command path to an address/command comparator, the address/command comparator being configured to compare the address/command data to an address/command receive source and generate an address/command loopback status output.

摘要： A digital delay-locked loop has been discovered having a reduced area as compared to typical register-controlled delay-locked loops (RDLLs) used to control strobe delay lines that provide delay to strobe signals driving asynchronous FIFOs. This result is achieved by reducing ratio computation (i.e. gear logic) circuitry of the RDLL. A master delay line receives a control code to delay a reference clock by one clock period. A slave delay line receives the control code to delay a strobe signal by a predetermined fraction of the clock period. The master delay line may include individual sections responsive to the control code which effectively delay a signal by a portion of the clock period, the delay having a fixed relationship to a delay associated with individual sections of the slave delay line.

摘要： An apparatus for canceling an effect of power supply resonance is provided. The effect of power supply resonance is a variation in power supply voltage potential. This variation may substantially affect an output buffer by causing the output buffer's output to sag below desired values. A voltage regulating circuit is coupled to power supply lines local to the output buffer where the voltage regulating circuit is most effective in reducing voltage potential variation. An exemplary voltage regulating circuit is provided that uses charge-pumped capacitors to raise the power supply voltage potential when it falls below a desired value. A second example of a voltage regulating circuit uses charge-pumped capacitors to lower the power supply voltage potential when it rises above a desired value.

摘要： A method for quantifying effects of resonance in an integrated circuit's power distribution network is provided. The power distribution network includes a first power supply line and a second power supply line to provide power to the integrated circuit. Test ranges are selected for two test parameters, reference voltage potential of a receiver and data transmission frequency of the integrated circuit. At each combination of the two test parameters, bit patterns are transmitted by the integrated circuit to the receiver. A comparison is made between the transmitted bits and the received bits to determine whether the transmitted bits were correctly received. The comparison may be used to determine and report a range of values for the reference voltage potential and data transmission frequency that allow the transmitted bits to be correctly received.

摘要： A calibration and adjustment system for post-fabrication control of a delay locked loop charge pump current is provided. The calibration and adjustment system includes an adjustment device that varies an amount of charge pump current. Such control of the charge pump current in a delay locked loop allows a designer to achieve a desired delay locked loop operating characteristic after the delay locked loop has been fabricated. A representative value of the amount of adjustment desired in the charge pump current may be stored and subsequently read to adjust the delay locked loop.
