MEMORY CIRCUIT AND METHOD OF OPERATING SAME
20250266113 · 2025-08-21 ·

A method of operating a memory circuit includes turning on a first programming device and turning on a first selection device thereby causing a first current to flow through a first fuse element. The first fuse element is coupled between the first selection device and the first programming device. The method further includes turning off a second programming device and turning off a second selection device, and blocking the first current from flowing through a second fuse element that is coupled between the second selection device and the first programming device.
