    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.

    摘要： Digital multilevel memory systems and methods include a charge pump for generating regulated high voltages for various memory operations. The charge pump may include a plurality of pump stages. Aspects of exemplary systems may include charge pumps that performs orderly charging and discharging at low voltage operation conditions. Additional aspects may include features that enable state by state pumping, for example, circuitry that avoids cascaded short circuits among pump stages. Each pump stage may also include circuitry that discharges its nodes, such as via self-discharge through associated pump interconnection(s). Further aspects may also include features that: assist power-up in the various pump stages, double voltage, shift high voltage levels, provide anti-parallel circuit configurations, and/or enable buffering or precharging features, such as self-buffering and self-precharging circuitry.
