The invention provides a lower-power consumption nonvolatile electronic programmable memory. According to the memory, a multi-level charge pump MLCP is decomposed into a plurality of cascaded charge pump groups; charging periodic signals are divided into a plurality of levels through a clock frequency dividing control circuit CKGEN by adoption of a time division manner so as to charge corresponding charge pump groups in sequence, so that control is carried out on a storage array when the output voltage VPP of the whole multi-level charge pump MLCP achieves a threshold value and then the storage array completes the storage and updating of the input data, thereby reducing the average write-in power consumption and realizing the restraint to the peak power consumption.
