Publication number: 20110090743Abstract: 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.Type: ApplicationFiled: December 28, 2010Publication date: April 21, 2011Inventors: Hieu Van Tran, Sang T. Nguyen, Anh Ly, Hung Q. Nguyen

Patent number: 7868604Abstract: 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.Type: GrantFiled: November 18, 2007Date of Patent: January 11, 2011Assignee: Silicon Storage Technology, Inc.Inventors: Hieu Van Tran, Sang Thanh Nguyen, Anh Ly, Hung Q. Nguyen, Wingfu Aaron Lau, Nasrin Jaffari, Thuan Trong Vu, Vishal Sarin, Loc B. Hoang
