Power noise reduction technique for high density memory with frequency adjustments
Memory devices may have internal circuitry that employs voltages higher than voltages provided by an external power source. Charge pumps are DC/DC converters that may be used to generate, internally, higher voltages for operation. The available charge pumps in a memory device may be adjusted through adjustment of the operation frequency of oscillating circuitry that drives the charge pump. Delay elements may also be adjusted to facilitate operation of the charge pump.
