Abstract
A FRAM configurable output driver circuit allows the user to configure the output driver for either CMOS level push/pull operation or true open drain operation. This configuration is stored in a non-volatile memory including a FRAM cell and a standard logic latch. The configuration data is restored to the latch on powerup. The user is able to change the configuration at any time. Any changes to the configuration are stored in the non-volatile memory.
