Abstract
According to the first embodiment of the present invention, a pre-charge device is connected to the middle of each complementary bit line. Thus, once activated, the pre-charge device only drives a load equal to half of the RC impedance of the entire bit lines during the pre-charging operation. According to the second embodiment of the present invention, a first pre-charge device is connected to one end of each complementary bit lines and a second pre-charge device is connected approximately to the middle of each complementary bit lines. Once both devices are activated, each device drives a load equal to half of the RC impedance of the entire bit lines, thus reducing the pre-charge time of the bit lines.
