These Burn & Learn chips contain no more than (3) failed devices or wire-bonds per chip, for a total of at least 13 fully functional memristors. These chips are rare and offered to researchers, when available, at a reduced cost.
These are Self-Directed-Channel (SDC) memristors with dopant (W, Cr, Sn) in a 32 DIP package, ideal for breadboarding. Chip-In-Board with optically clear glob-top allows for microscopic inspection of memristor die. Breadboard not included. Variant (W,Cr,Sn) is picked by us depending on availability.
For more information about the device properties and precautions to take while working with our memristors download the Knowm Memristors Data Sheet.
Note: Not suitable for sustained high temperatures due to resin encapsulate. For high temperature experiments please use ceramic packages.

The first time a device is operated after fabrication the self-directed channel is formed during application of a positive potential to the top electrode. The potential required for this operation is typically the same as required during normal device operation. This first operation generates Sn ions from the SnSe layer and forces them into the ‘active’ Ge2Se3 layer, where they undergo a chemical reaction. During this reaction, the glass network is distorted to provide conductive channels for the movement of Ag+ during device operation. The resistance is tunable in the lower and higher directions by movement of Ag into or away from these channels through application of either a positive or negative potential, respectively, across the device. Knowm memristors are Ag+ ion SDC memristor where the active layer has been doped to enhance and optimize the memristors properties.
