Abstract
The invention relates to a DNR (differential negative resistance) exhibiting device that can be programmed to store information as readable current amplitudes and to methods of making such a device. The stored data is semi-volatile. Generally, information written to a device in accordance with the invention can maintain its memory for a matter of minutes, hours, or days before a refresh is necessary. The power requirements of the device are far reduced compared to DRAM. The memory function of the device is highly stable, repeatable, and predictable. The device can be produced in a variety of ways.
