An improved power fail-safe has an effective maximum delay of two gate delays from an input operably powered by a first power supply to a first and a second output operably powered by a second power supply. The first and second outputs have predetermined values during an interval when the first power supply has failed and the second power supply is active. The first and second power supplies may be based at least in part on different power domains. The first power supply may be based at least in part on a core power domain and the second power supply may be based at least in part on an I/O power domain.

Reduced delay power fail-safe circuit

The present invention relates to a method and apparatus for a reconfigurable multi-chip module. The reconfigurable multi-chip module includes a processor; a memory module connected to the processor; and a memory control component for controlling whether the processor uses the memory module. The method of producing multi-chip modules includes assembling a processor and a memory module on the multi-chip module; testing the memory module; and selectively configuring the processor to use the memory module based on the testing of the memory module.
