摘要:
The present invention relates to a semiconductor memory device for sensing voltages of bit lines in high speed. The semiconductor memory device for sensing voltages of bit lines in high speed includes: a first bit line pair to a fourth bit line pair each coupled to a different unit cell array; a bit line sense amplifying means coupled to the first bit line pair to the fourth bit line pair for amplifying data transmitted through the first bit line pair to the fourth bit line pair; and a switching block for connecting one of the first bit line pair to the fourth bit line pair with the bit line sense amplifying means in response to a control signal.
