摘要： Memory elements are provided that exhibit immunity to soft error upset events when subjected to radiation strikes such as high-energy atomic particle strikes. Each memory element may each have four inverter-like transistor pairs that form a bistable element, a pair of address transistors, and a pair of relatively weak transistors connected between two of the inverters that create a common output node which is resistant to rapid changes to its state. The transistors may be connected in a pattern that forms a bistable memory element that is resistant to soft error upset events due to radiation strikes. Data may be loaded into and read out of the memory element using the address transistor pair.

摘要： Integrated circuits such as programmable logic device integrated circuits are provided that have configuration random-access memory elements. The configuration random-access memory elements are loaded with configuration data to customize programmable logic on the integrated circuits. Each memory element has a capacitor that stores data for that memory element. A pair of cross-coupled inverters are connected to the capacitor. The inverters ensure that the memory elements produce output control signals with voltages than range from one power supply rail to another. Each configuration random-access memory element may have a clear transistor. The capacitor may be formed in a dielectric layer that lies above the transistors of the inverters, the address transistor, and the clear transistor. The inverters may be powered with an elevated power supply voltage.

摘要： Memory elements are provided that exhibit immunity to soft error upsets. The memory elements may have cross-coupled inverters. The inverters may be implemented using programmable Schmitt triggers. The memory elements may be locked and unlocked by providing appropriate power supply voltages to the Schmitt trigger. The memory elements may each have four inverter-like transistor pairs that form a bistable element, at least one address transistor, and at least one write enable transistor. The write enable transistor may bridge two of the four nodes. The memory elements may be locked and unlocked by turning the write enable transistor on and off. When a memory element is unlocked, the memory element is less resistant to changes in state, thereby facilitating write operations. When the memory element is locked, the memory element may exhibit enhanced immunity to soft error upsets.

摘要： Asymmetric transistors may be formed by creating pocket implants on one source-drain terminal of a transistor and not the other. Asymmetric transistors may also be formed using dual-gate structures having first and second gate conductors of different work functions. Stacked transistors may be formed by stacking two transistors of the same channel type in series. One of the source-drain terminals of each of the two transistors is connected to a common node. The gates of the two transistors are also connected together. The two transistors may have different threshold voltages. The threshold voltage of the transistor that is located higher in the stacked transistor may be provided with a lower threshold voltage than the other transistor in the stacked transistor. Stacked transistors may be used to reduce leakage currents in circuits such as memory cells. Asymmetric transistors may also be used in memory cells to reduce leakage.
