What is PMCm?
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.
