The world’s smallest memory is Made in Grenoble

Leti researchers have built a 16-nm charge-storage memory—the smallest ever cited in the literature. Until now, the most advanced memory systems measured 40 nm. Even better, the tiny new memory has already been demonstrated to work, offering the necessary temperature and cycling stability, not to mention low power consumption. The memory could be used for embedded systems in the automotive industry, for example.
The researchers used a split-gate architecture that has been patented for a decade, and added spacers to eliminate a costly lithography step. They controlled the memory grid’s shape and length to ensure good electrical performance. A total of five patents have been filed to protect the invention; talks are underway with manufacturers.
