摘要:
A device that includes an electronic device referred to as an integrated circuit interposer is disclosed. The integrated circuit includes a voltage regulator module. The interposer is attached to an electronic device, such as another integrated circuit, and facilitates control and distribution of power to the electronic device. The integrated circuit interposer can also conduct signaling between the attached electronic device and another electronic device. The voltage regulator module at the integrated circuit interposer can be configured to provide a voltage reference signal to the attached electronic device. Generation of the voltage reference signal by the integrated circuit interposer can be enabled or disabled and the value of the voltage reference signal can be adjusted, depending on operating requirements of the electronic device.

A method, apparatus, computer chip, circuit board, computer and system are provided in which data is stored in a low-voltage, maskable memory. Also provided is a computer readable storage device encoded with data for adapting a manufacturing facility to create an apparatus. The method includes storing a data value in a memory cell in a storage device if a first access parameter associated with the memory cell matches a first pre-determined value and if a second access parameter associated with the memory cell matches a second pre-determined value. The method also includes maintaining a data value in the memory cell in the storage device if the first access parameter differs from the first pre-determined value. The apparatus includes a first and second pair of access parameter ports operatively coupled together and associated with a first and second access parameter respectively. The first and second pair of access parameter ports may be adapted to allow access through the first and second pair of access parameter ports if the first access parameter matches a first pre-determined value, and if the second access parameter matches a second pre-determined value.

A circuit incorporating a current starved ring oscillator is coupled to a power gate switch in an integrated circuit. The circuit incorporating the current starved ring oscillator amplifies a voltage difference between a virtual ground associated with the power gate switch and ground, and converts the difference to a frequency. Digital logic monitors the output of the ring oscillator using a counter and a reference clock. Control circuitry controls operation of the integrated circuit in dependence on the monitored conditions associated with the power gate switch. A method monitors a virtual ground voltage across a power gate switch in an integrated circuit; and controls operation of the integrated circuit in dependence on the monitored virtual ground voltage.

A memory cell comprises a wordline, a first digital inverter with a first input and a first output, and a second digital inverter with a second input and a second output. Moreover, the memory cell further comprises a first feedback connection connecting the first output to the second input, and a second feedback connection connecting the second output to the first input. The first feedback connection comprises a first resistive element and the second feedback connection comprises a second resistive element. What is more, each digital inverter has an associated capacitance. The memory cell is configured such that reading the memory cell includes applying a read voltage pulse to the wordline. In addition, the first and second resistive elements are configured such that the first and second feedback connections have resistance-capacitance induced delays longer than the applied read voltage pulse.

An integrated circuit, such as a memory macro, includes multiple power rails supporting first and second voltage differentials, with the second voltage differential being smaller than the first voltage differential. Signal lines in the integrated circuit are driven with the small voltage swing, which is generated by small swing circuits. The integrated circuit further includes regeneration circuits, which are receiving small voltage swing inputs and are outputting first, or full voltage swings. The application of the small voltage swing to the signal lines saves power in the integrated circuit. A wide bandwidth, full-wordline I/O, memory integrated circuit has simultaneously operable connection paths between essentially all the memory cells that are attached to the same wordline and the corresponding I/O terminals, and it has a single ended data-line structure.
