What is PMCm?

The Programmable Metallization Cell is a simple and elegant structure that operates as very effective non-volatile memory (NVM). The size and production process is compatible with the technology used to fabricate the smallest transistors. The mechanism that defines memory behavior is a proprietary Axon process and uses a thin amorphous film with 2 metal contacts. It makes use of a little-known feature of some amorphous materials that they can incorporate relatively large amounts of metal and behave as solid electrolytes. Under appropriate bias conditions, the metal ions in the electrolyte can be reduced to form a conducting pathway through the material but the process can easily be reversed to recreate the insulating amorphous layer.
