ABSTRACT:
A semiconductor memory device comprises active pull-up circuits (APU.sub.1, APU.sub.2) each provided for one bit line (BL.sub.1, BL.sub.1). Each active pull-up circuit (APU.sub.1) has connections to two bit lines. That is, an active pull-up circuit (APU.sub.1) for a first bit line (BL.sub.1) comprises a first transistor (Q.sub.1) connected between a power supply terminal (V.sub.CC) and the first bit line, a second transistor (Q.sub.2) connected between the gate of the first transistor and the first bit line, and a capacitor (C.sub.1) connected to the gate of the first transistor. The gate of the second transistor is connected to a second bit line (BL.sub.1) which is paired with the first bit line. The capacitor receives an active pull-up signal (.phi..sub.AP). A circuit (Q.sub.3, Q.sub.4, Q.sub.5) is provided for transmitting a high level potential to the gate (N.sub.1) of the first transistor to precharge the capacitor.
