Abstract
Programmable logic devices are provided having configuration memory cells that exhibit decreased soft error rates. A stabilizing capacitor may be connected between each of the memory cell's input and output terminals. The capacitor may be a metal-insulator-metal capacitor formed using a vertical structure, a horizontal structure, or a hybrid vertical-horizontal structure. The memory cell may have inverter transistors of increased strength to help stabilize the memory cell.
