Power noise reduction technique for high density memory with gating
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 number of available charge pumps in a memory device may be higher than the number used for certain memory operations. Gating circuitry may be used to selectively enable charge pump cores based on power demands that may be associated with a mode of operation and/or a command.
