Abstract
A semiconductor device includes: a first sense amplifier; a first bit line coupled to the first sense amplifier; a second bit line disposed next to the first bit line and electrically coupled to a constant-voltage source; and a first reference cell, including: a first transistor having a source and a drain, one of which is coupled to the first bit line; a second transistor, having a source and a drain, one of which is coupled to the second bit line, and the other coupled to the other of the source and drain of the first transistor, which is not coupled to the bit line BL1a; and a capacitance C1 having electrodes, one of which is coupled to the other of the source and the drain of the first transistor, and the other of the source and the drain of Tr2.

A semiconductor device, comprising:
- a first bit line;
- a second bit line disposed to be next to said first bit line;
- and
- a first reference cell, including:
- a first transistor having a source and a drain, one of said source and said drain being coupled to said first bit line;
- a second transistor having a source and a drain, one of said source and said drain being coupled to said second bit line, and the other being coupled to the other of said source and said drain of said first transistor, which is not coupled to said first bit line;
- and
- a first capacitance having electrodes, one of said electrode being coupled to said other of said source and said drain of said first transistor, which is not coupled to said first bit line, and also being coupled to said other of said source and said drain of said second transistor, which is not coupled to second first bit line.
