Patent number: 6980448Abstract: A circuit for providing an output voltage for a DRAM word line which can be used to drive memory word lines which can be as high as 2Vdd. Transistors in a boosting circuit are fully switched, eliminating reduction of the boosting voltage by Vtn through the transistors. The boosting capacitors are charge by Vdd. A regulator detects conduction current of a replica of a memory cell access transistor, shutting off the boosting circuit clock oscillator when the correct voltage to operate the access transistor has been reached.Type: GrantFiled: June 17, 2003Date of Patent: December 27, 2005Assignee: MOSAID Technologies, Inc.Inventors: Richard C. Foss, Peter B. Gillingham, Robert F. Harland, Valerie L. Lines
