Abstract
Embodiments of the present technology provide memory cards intelligently designed to provide protection when mistakenly inserted into non-memory card hosts. Embodiments achieve such protection with less footprint/circuitry than existing fail-safe solutions, and without electrical overstress-causing offset voltages characteristic of existing fail-safe solutions. To realize these advantages, a memory card of the present technology includes a fail-safe reference voltage supply circuit that operates in a 'fail-safe mode' by default, and exits and re-enters the fail-safe mode in response to voltage mode driver output enable (OE) signals.
