    摘要: A memory system includes a sense amplifier for detecting content of data memory cells by comparison with a voltage stored in a reference cell. The sense amplifier may comprise a comparator, first and second load circuits, and a low impedance circuit. A first input of the comparator is coupled to the low impedance circuit and a reference voltage node. A second input of the comparator is coupled to a data voltage node. The first load circuit loads a reference cell coupled to the reference voltage node. The second load circuit loads a data cell coupled to the data voltage node.

    摘要: Various circuits include MOS transistors that have a bulk voltage terminal for receiving a bulk voltage that is different from a supply voltage and ground. The bulk voltage may be selectively set so that some MOS transistors have a bulk voltage set to the supply voltage or ground and other MOS transistors have a bulk voltage that is different. The bulk voltage may be set to forward or reverse bias pn junctions in the MOS transistor. The various circuits include comparators, operational amplifiers, sensing circuits, decoding circuits and the other circuits. The circuits may be included in a memory system.

    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.
