Patent ID: 7212427

Claim:
A ferroelectric, non-volatile memory comprising: a plurality of pairs of parallel bit lines and a plurality of memory cells arranged rows and columns, said columns parallel to said bit lines and said rows perpendicular to said bit lines, each said memory cell associated with one of said pairs of bit lines, each said memory cell comprising: a first ferroelectric capacitor having a first electrode and a second electrode, a second ferroelectric capacitor having a first electrode and a second electrode, a first transistor having a gate, and a second transistor having a gate; wherein in each said memory cell said first transistor is connected between said first electrode of said first capacitor and one of said bit lines in said associated bit line pair, and said second transistor is connected between said first electrode of said second capacitor and the other of said bit lines in said associated bit line pair; said memory further including a plurality of drive lines and a drive line transistor associated with each of said drive lines, with each of said memory cells associated with one of said drive lines, said drive line transistor including a gate, said drive lines being parallel to said bit lines, each of said drive lines connected to the second electrode of said first and second ferroelectric capacitors in said memory cell associated with said drive line via said drive line transistor, there being at least one of said drive line transistors in each of said rows, and each of said drive lines connected to two or less of said memory cells in said row, said memory further including a word line perpendicular to said bit line pairs and said drive lines, and said gates of said first transistor, said second transistor and said drive line transistor connected to said word line, and wherein one of said drive lines is associated with each of said cells, and said drive line is located between said bit lines in said bit line pair associated with said cell with which said drive line is associated.
