摘要： A digital multilevel memory system includes a charge pump and a voltage regulator for generating regulated high voltages for various memory operations. The charge pump may include a plurality of boost circuits to boost the output of the charge pump during a fast start up. Afterwards, the boost circuits are disabled to allow the charge pump to generate high voltages without boosting. The boost circuits may be successively enabled to boost the voltage. The boost circuits may be loadless. The voltage regulator may operate in an open loop and may include a resistive divider as a reference voltage for regulating the high voltage from the charge pump. The charge pump may include spread spectrum pump clocking to reduce electromagnetic inference for capacitor or inductor on-chip charge pumping.

The cells in the same column have a common bit line connected to the first terminal of memory cells in the same column. The array comprises a first and second sub arrays of memory cells arranged adjacent to one another in the same row. A first decoder is positioned to one side of the first sub array in the same row as the first sub array. A second decoder is positioned to another side of the second sub array in the same row as the second sub array. A first high voltage line is connected to the second decoder and to only the second terminal of the memory cells in the same row in the first sub array. A second high voltage line, different from the first high voltage line, is connected to the second decoder and to only the second terminal of the memory cells in the same row in the second sub array. A low voltage line is connected to the first decoder and to the thirds terminal of the memory cells in the same row of the first and second sub arrays.
