Abstract:
In interplanetary space, the Cassini Solid-State Recorder is experiencing the predicted number of upsets, but a very high rate of uncorrectable errors. An experimental investigation of the flight DRAM's susceptibility to multiple-bit upset (MBU) proved enlightening, revealing an unexpectedly high rate of MBU's (even caused by protons). In combination with an architectural flaw in the error correction circuitry, these explain the flight anomaly.
