Claim:
1. A method for controlling a ramp rate of an output voltage from one or more charge pumps, comprising: determining a memory operation to be performed on a memory array; determining a final regulation voltage based on the memory operation; determining a ramp rate schedule associated with controlling the ramp rate of the output voltage from the one or more charge pumps based on the memory operation, the ramp rate schedule specifies a first voltage level associated with a first time, the first voltage level is less than the final regulation voltage; detecting that the output voltage from the one or more charge pumps is greater than the first voltage level prior to the first time; and disabling the one or more charge pumps in response to detecting that the output voltage is greater than the first voltage level prior to the first time, wherein disabling the one or more charge pumps includes preventing the one or more charge pumps from increasing the output voltage above the first voltage level less than the final regulation voltage.
