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： 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： A programmable logic device integrated circuit or other integrated circuit may have logic circuitry that produces data signals. The data signals may be routed to other logic circuits through interconnects. The interconnects may be programmable. A level recovery circuit may be used at the end of each interconnect line to strengthen the transmitted data signal. The level recovery circuit that is attached to a given interconnect line may produce true and complementary versions of the data signal that is on that interconnect line. Level shifting circuitry may be provided to boost the data signals on the interconnects. Each interconnect line may have a level shifter circuit that receives the true and complementary versions of a data signal and that produces corresponding boosted true and complementary versions of the data signal. The boosted signals may be provided to the control inputs of complementary-metal-oxide-semiconductor transistor pass gates in programmable look-up table circuitry.

摘要： An integrated circuit with memory elements is provided. The memory elements may have memory element transistors with body terminals. Body bias control circuitry may supply body bias voltages that strengthen or weaken memory element transistors to improve read and write margins. The body bias control circuitry may dynamically control body bias voltages so that time-varying body bias voltages are supplied to memory element transistors. Address transistors and latch transistors in the memory elements may be selectively strengthened and weakened. Process variations may be compensated by weakening fast transistors and strengthening slow transistors with body bias adjustments.
