Abstract
A memory controller for a memory card such as an SD card with an additional host interface such as a USB interface comprises a duplicate SD interface. Embodiments with two SD interfaces may also comprise a card reader controller chip that can be turned off by the memory controller when the USB interface is not needed. Incorporation of the additional SD interface in the controller allows for an economical or off the shelf card reader controller to be employed.
