Multi-bit memory cell using long-range non-anchored actuation for high temperature applications

摘要

A novel micro-electro-mechanical (MEM) based non-volatile memory (NVM) is proposed. The storage principle is based on Lorentz's transduction, utilizing long-range motion of a non-anchored element which has current carrying sliding contact with a conductive path. Position of the moving element indicates the stored data in the multi-bit cell. Data is written in the cell with displacing the moving element by Lorentz's force, is read by utilizing differential port resistances, and is held by adhesion forces. Data writing at up to, and data retention and reading for higher temperatures are reliable.
