Memory device with a built-in memory array and a connector for a removable memory device

A memory device comprising:

• a built-in memory array;
• a first connector configured to connect to (i) a removable memory device comprising a memory array and a memory controller and (ii) a removable memory device comprising a memory array without a memory controller;
• a second connector configured to connect to a host device;
• and
• circuitry operative to determine if a removable memory device connected to the first connector comprises a memory controller;
• wherein the circuitry is further operative to control read/write operations to the removable memory device's memory array if the circuitry determines that the removable memory device does not comprise a memory controller;
• wherein when a connected removable memory device does not comprise a memory controller, the memory device functions as a hybrid memory device to transfer data between the built-in memory array in the memory device and the memory array in the removable memory device, and wherein when a connected removable memory device comprises a memory controller, the memory device functions as an adapter for the removable memory device with the memory device acting as a passive pass-through between the host device and the removable memory device.
