Abstract
A memory device comprising multiple memory planes is disclosed. The memory device further comprises a first pump set coupled with the multiple memory planes, and configured to supply a first output voltage to multiple linear regulators during a steady phase, and a second pump set coupled with the multiple memory planes, and configured to supply a second output voltage to the multiple linear regulators during a ramping phase. The multiple linear regulators can includes a first linear regulator set configured to regulate the first output voltage or the second output voltage to generate a first voltage bias for a first group of word lines of the plurality of memory planes, and a second linear regulator set configured to regulate the first output voltage or the second output voltage to generate a second voltage bias for a second group of word lines of the plurality of memory planes.
