The solid state storage card comprises an interface to the host controller, processor core, volatile memory, and non-volatile memory. Upon receipt of a core dump triggering event, the processor core copies execution state data from a register of the processor core to a buffer in the volatile memory and writes core dump data of the buffer to the non-volatile memory. The host controller reads the core dump data from the solid state storage card's non-volatile memory through the interface.
