Abstract
During standby, bit lines BL,and /BL,are precharged, and the potentials of word lines WL,and WL,are set at a potential slightly higher than a ground potential. Since a stable retaining current flows through an access transistor into a node inside a memory cell holding the H level, the data can be retained with stability. Moreover, during an access, the selected word line is brought to the H level, while the unselected word lines are brought to a ground potential.
