Abstract: An electronic device includes an input/output (I/O) interface and a plurality of memory elements comprising a non-volatile memory portion for storing a default firmware and a working memory portion having a firmware area. The device also includes a controller coupled to the I/O interface and the memory elements, where the controller is configured for operating the memory elements, according to the firmware area, and for monitoring the I/O interface. In the device, the controller is also configured for loading the default firmware into the firmware area when the controller is enabled and for granting access to the firmware area for loading an alternate firmware if a bypass code is detected at the I/O interface.

Abstract: An electronic device is provided including an input/output (I/O) interface, a plurality of memory elements, a controller coupled to the I/O interface and the plurality of memory elements. In the device, the controller configured for operating the plurality of memory elements during a normal operating mode of the electronic device, where responsive to receiving a command for replacing a selected memory sector in the electronic device during the normal operating mode, the controller is configured for identifying one or more available spare memory sectors in the electronic device and modifying at least one memory map in the electronic device to replace the selected memory sector with the one of the available spare memory sectors.
