Repeatedly accessing a row in recent DRAM devices can cause bit flips in adjacent rows, and attacks demonstrated and documented by the Google Project Zero team have used this behavior to gain kernel privileges on x86-64 Linux machines (from unprivileged user-land).
Working with Bellcore's Boneh and Richard DeMillo, Lipton showed in principle how random bit flips could be exploited to deduce the secret key in the RSA cryptographic scheme when used in a smart card.
iRoC Technologies, a leader in the field of Infrastructure IP, announced today the release of the beta version of M-RoCKIT(TM), a new technology platform for automated generation, interconnection and insertion of advanced error correcting code (ECC) for protection against bit flips in embedded memories.
Increased sensitivity of memories to bit flips for new technologies together with an increased amount of Mbits of memories on SoCs -- Increased diversity of memories in SoCs (over 100 memory types).
NASA and Boeing are among the organizations who devote considerable engineering efforts to the "hardening" of electronic devices designed to operate in harsh environments to protect them against random bit flips, singe event upsets in semiconductor chips due to cosmic rays or naturally-occurring radioactive elements in packaging materials.
With no speed penalty, the device automatically corrects bit flips due to radiation particle strikes.
About one bit flips per every 1,000 to 2,500 instructions copied, adding variation to the daughter cell.
