Methods and apparatus related to supporting both DDR (Double Data Rate) and NVM (Non-Volatile Memory) DIMM (Dual Inline Memory Module) on the same memory slot are described. In one embodiment, a DIMM comprises volatile memory and non-volatile memory, and data is communicated with the volatile memory and the non-volatile memory via a single memory slot. Other embodiments are also disclosed and claimed.

Supporting multiple memory types in a memory slot

In one embodiment, the present invention includes a primary voltage regulator to couple a regulated voltage to a processor via a supply line. This regulator includes a multi-phase controller to provide the regulated voltage in multiple phases and to provide a maximum current output sufficient to meet a thermal design power (TDP) of the processor. In addition, an auxiliary voltage regulator may be configured to provide an excess current to the processor via the supply line for a time limited duration, e.g., based on the supply line state. Other embodiments are described and claimed.

Providing additional current capacity to a processor for a turbo mode

Briefly, in accordance with one embodiment of the invention, a circuit includes: a DC-to-DC converter. The DC-to-DC converter includes a plurality of ripple regulator DC-to-DC converter circuits. The plurality of circuits are coupled so that the output signals produced by each of the ripple regulator DC-to-DC converter circuits is out of phase with respect to the other of the ripple regulator DC-to-DC converter circuits.

Phased ripple DC-to-DC converter

Briefly, in accordance with one embodiment of the invention, a DC-to-DC converter includes: a circuit configuration to modify the set point of the output voltage signal level of the DC-to-DC converter circuit in response to a transient signal by an amount related, at least in part, to the magnitude of the transient signal. Briefly, in accordance with yet another embodiment of the invention, a DC-to-DC converter circuit includes: a high-side and a low-side voltage switching device. The switching devices are coupled in a circuit configuration to apply a control voltage signal to each switching device based, at least in part, on the state of the other switching device.

DC-to-DC converter

A power supply including a DC&mdash;DC converter with multiphase current sharing and ripple regulation. In one embodiment, the disclosed power supply includes a plurality of power drivers coupled to supply power to the supply output. The power drivers are cyclically enabled to provide multiphase current sharing. Ripple regulation is provided with a hysteretic comparator that is coupled to receive feedback from the power supply output. The hysteretic comparator is used to clock or advance a select circuit, which is used to cyclically enable each one of the plurality of power drivers. A reset circuit is included to reset the hysteretic comparator in the event that the hysteretic comparator has not switched for an excessive amount of time. A supply current sensor is used to monitor the current drawn by the plurality of power drivers. As the amount of current drawn by any of the plurality of power drivers rises, the on cycle time of the power driver that is delivering power to the power supply output at that particular time is shortened, enabling the next power driver to deliver power.
