Abstract
A data recorder for permanently storing pre-event data may include a read-write memory with a plurality of bit cells in the read-write memory. Each bit cell may have a bit state of a high value or a low value. A fusible structure in the data recorder may include a morphable element associated with each bit cell. A temperature-triggered module may thermally couple to the ambient environment and may electrically couple to each morphable element. The temperature-triggered module may be further configured to determine if a parameter of the ambient environment exceeds a predetermined threshold, and if so may then transmit a burn signal to the fusible structure so that each morphable element permanently secures the bit state for each bit cell.
