Abstract
A kill switch is provided that, when triggered, may cause the programmable logic device (PLD) to become at least partially reset, disabled, or both. The kill switch may be implemented as a fuse or a volatile battery-backed memory bit. When, for example, a security threat is detected, the switch may be blown, and a reconfiguration of the device initiated in order to zero or clear some or all of the memory and programmable logic of the PLD.
