ABSTRACT:
A semiconductor memory device has a memory cell array having a plurality of memory cells connected to multiple word lines and between multiple pairs of bit lines. A main sense amplifier reads cell information onto a pair of bit lines from one memory cell selected via a word line and outputs the read cell information after amplification. A pre-sense amplifier, connected to each pair of bit lines, amplifies a potential difference between the pair of bit lines based on the cell information and outputs the amplified potential difference to the main sense amplifier prior to outputting of the read data.
