摘要:
For one disclosed embodiment, an apparatus comprises a load circuit having one or more memory devices, one or more temperature sensors to sense one or more temperatures for the load circuit, and supply voltage control circuitry to control supply voltage to be applied to the load circuit. The supply voltage control circuitry may vary the supply voltage based at least in part on one or more sensed temperatures when the load circuit is in an inactive state and may help retain one or more signals by one or more memory devices of the load circuit as the supply voltage is varied. Other embodiments are also disclosed.

Power switch units for microelectronic devices are disclosed. In one aspect, a microelectronic device may include a functional circuit, and a power switch unit to switch power to the functional circuit on and off. The power switch unit may include a large number of transistors coupled together. The transistors may include predominantly positive-channel, insulated gate field effect transistors, which have a gate dielectric that includes a high dielectric constant material. Power switch units having such transistors may tend to have low power consumption. In an aspect, an overdrive voltage may be applied to the gates of such transistors to further reduce power consumption. Methods of overdriving such transistors and systems including such power switch units are also disclosed.
摘要:
A method comprising running an error correction code on data and storing the data and the result of the error correction code in memory, running an error correction code on the data when it is read from the memory, comparing the results of the error correction codes on the data from before and after the memory, correcting errors when the comparator determines a difference in the results of the error correction codes and lowering the operating voltage of the memory array while using the error correction.

In general, in one aspect, the disclosure describes a semiconductor device that includes a functional circuit and a dc-to-dc power converter. The power converter converts, regulates, and filters a DC input voltage to produce a DC output voltage and provides the DC output voltage to the functional circuit. The dc-to-dc power converter has an operating frequency above 10 MHz.
