Abstract
A Flash memory controller includes a host interface, a Flash memory interface, controller logic coupled between the host interface, the controller logic handling a plurality of voltages. The controller also includes a mechanism for allowing a multiple voltage host to interface with a high voltage or multiple voltage Flash memory. A multiple voltage Flash memory controller in accordance with the present invention provides the following advantages over conventional Flash memory controllers: (1) a voltage host is allowed to interface with multiple Flash memory components that operate at different voltages in any combination; (2) power consumption efficiency is improved by integrating the programmable voltage regulator, and voltage comparator mechanism with the Flash memory controller; (3) External jumper selection is eliminated for power source configuration; and (4) Flash memory controller power source interface pin-outs are simplified.
