Publication number: 20060280011Abstract: Voltage coupling/decoupling devices are provided within DRAM devices for improving the bias sensing of sense amplifiers and thus the refresh performance. The voltage coupling/decoupling devices couple or decouple bias voltage from corresponding digit lines coupled to the sense amplifiers. By coupling and decoupling voltage from the digit lines, the time interval between refresh operations can be increased.Type: ApplicationFiled: June 13, 2006Publication date: December 14, 2006Inventors: David McElroy, Stephen Casper
