<p>A removable controller card comprised of a plurality of Flash EEPROM devices (24) and a controller device (20) is described. The controller device (20) is further comprised of voltage detection circuitry including a variable voltage detector (28) for determining the system voltage level provided by a power supply within a computer (25) and for appropriately enabling a voltage regulator circuit (30) for dividing the system voltage level to a level suited for operation by the Flash EEPROM devices (24) and applying this operational voltage level to the Flash EEPROM devices (24). Upon determining the system voltage level provided by the power supply to be appropriately suited for operation of the Flash EEPROM devices (24), disabling the voltage regulator circuit (30) and providing the system voltage level to the Flash EEPROM devices (24).</p> |
