ADAPTIVE VOLTAGE INPUT TO A CHARGE PUMP

摘要

A memory subsystem includes an adaptive output voltage to provide a voltage based on a power profile of a memory device of the memory subsystem. A charge pump increases the voltage to a level needed to write data to the memory device. The voltage provided is based on the power profile of the memory device, which indicates a voltage level that provides good efficiency for the charge pump, and is within maximum levels for the memory device. The voltage can be higher than a nominal voltage indicated for the memory device in a specification.

1. A memory subsystem comprising:
a memory device to store data, the memory device to receive an input voltage at a first voltage level, wherein writing data to the memory device uses a second voltage level higher than the first voltage level; a charge pump to increase the input voltage from the first voltage level to the second voltage level; and an adaptive voltage supply to provide the first voltage level based on a power profile of the memory device, the power profile indicating a maximum input voltage level for the memory device.
