Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY LTD.
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 14:
15. A method of operating a sense amplifier circuit, the method comprising:
in a first operational mode:
coupling first and second terminals of a first capacitive device to first and second data lines, respectively, wherein the second terminal of the first capacitive device comprises a first input terminal of a sense amplifier;
coupling first and second terminals of a second capacitive device to the second and first data lines, respectively, wherein the second terminal of the second capacitive device comprises a second input terminal of the sense amplifier; and

in a second operational mode:
decoupling the first and second terminals of each of the first and second capacitive devices from each of the first and second data lines;
coupling the first terminals of each of the first and second capacitive devices to a reference voltage node; and
using the sense amplifier to detect a voltage difference between the first and second data lines.
