    Abstract: A memory device includes an address generator which generates a first physical address and a second physical address different from the first physical address. A first nonvolatile memory includes the first physical address, and a second nonvolatile memory includes the second physical address. An attack detecting circuit detects whether the first and second nonvolatile memories are attacked. The attack detecting circuit receives first data from the first nonvolatile memory and receives second data from the second nonvolatile memory, compares the first data and the second data with each other, and determines whether the first and second nonvolatile memories are attacked on the basis of a comparison result of the first data and the second data.

    Abstract: Methods and systems of detection of wafer de-chucking in a semiconductor processing chamber are disclosed. Methods and systems of interdiction are also disclosed to prevent hardware and wafer damage during semiconductor fabrication if and when de-chucking is detected. In one embodiment, a de-chucking detection method is based on measuring change in imaginary impedance of a plasma circuit, along with measuring one or both of reflected RF power and arc count. In another embodiment, a possibility of imminent de-chucking is detected even before complete de-chucking occurs by analyzing the signature change in imaginary impedance.
