Abstract
A computer card including a voltage detection circuit having Flash EEPROM devices and a controller device, the voltage detection circuit further including a variable voltage detector for determining the system voltage level provided by a power supply within the computer product and appropriately enabling a voltage regulator circuit for dividing the system voltage level to a level suited for operation by the Flash EEPROM devices and applying this operational voltage level to the Flash EEPROM devices. Upon determining the system voltage level provided by the power supply to be appropriately suited for operation of the Flash EEPROM devices, disabling the voltage regulator circuit and providing the system voltage level to the Flash EEPROM devices.
