SEMICONDUCTOR MEMORY DEVICE AND METHOD FOR THE OPERATION

摘要

PURPOSE: A semiconductor memory device and a method for the operation are provided to improve the offset electric potential of a bit line sense amplifier by removing floating state. CONSTITUTION: In a semiconductor memory device and a method for the operation, a bit line amplifier(10) sense and amplifies data loaded in a bit lien pair. A power line equalize signal generator(310) generates a power line equalize signal A power line equalize unit(13) supplies a precharge to the pull-up power line and the pull-down power line. A pull up driver(11) drives the pulls-up power line with a pull-up voltage. A pull down driver drives the pulls-down power line with a pull-down voltage.
