Patent ID: 6954389

Claim:
A dynamic semiconductor storage device, comprising: a first shared line; a second shared line paired with said first shared line; a first bit line; a second bit line paired with said first bit line; a third bit line; a fourth bit line paired with said third bit line; a first isolator connected between said first and second shared lines and said first and second bit lines; a second isolator connected between said first and second shared lines and said third and fourth bit lines; a first sense amplifier connected between said first and second shared lines; and second and third sense amplifiers; wherein said second sense amplifier includes: a first field effect transistor having a gate connected to said first bit line and a drain connected to said second shared line; and a second field effect transistor having a gate connected to said second bit line and a drain connected to said first shared line; and wherein said third sense amplifier includes: a third field effect transistor having a gate connected to said third bit line and a drain connected to said second shared line; and a fourth field effect transistor having a gate connected to said fourth bit line and a drain connected to said first shared line.
