Hybrid volatile and non-volatile memory device

Non-transitory computer-readable media having information embodied therein, the information including instructions for an integrated circuit device to execute a method comprising:

• writing data to a first addressable range of storage cells, the first addressable range of storage cells formed in a volatile memory die;
• detecting a triggering event associated with the written data;
• and
• in response to the triggering event, transferring at least a portion of the written data from the first addressable range of storage cells to a second addressable range of storage cells, the second addressable range of storage cells formed in a non-volatile memory die and defining an overlapping region with the first addressable range of storage cells.

Non-transitory computer-readable media storing having information embodied therein that includes a description of an integrated circuit device, the information comprising descriptions of:

• a memory controller;
• a memory coupled to the memory controller, the memory including
• a volatile storage die having a first addressable range of storage cells;
• a non-volatile storage die having a second addressable range of storage cells that defines an overlapping region with the first addressable range of storage cells;
• and
• an interface circuit coupled to the volatile and non-volatile storage die to selectively transfer data stored in the overlapping region of storage cells between the die.
