A method for using a memory device with a built-in memory array and a connector for a removable memory device is disclosed. In one embodiment, a determination is made regarding whether a removable memory device comprises a memory controller. If the removable memory device does not comprise a memory controller, circuitry in a memory device connected to the removable memory device is used to control read/write operations to a memory array in the removable memory device. In another embodiment, data stored in a built-in memory of a memory device is read, and the read data is stored in a memory array of a removable memory device. In yet another embodiment, a connection of a removable memory device to a memory device is detected. Pre-loaded content is read from a memory array in the removable memory device and stored in the built-in memory array of the memory device.
