PRESS RELEASE: VTT develops a method for printing WORM memories
VTT has developed a method for printing memory circuits directly, e.g. onto consumer packaging. Because the required production technology is quite simple, no major investments are required. The write-once-read-many (WORM) memories can be fabricated directly on the product or packaging using flexographic or inkjet printing machines, common in the packaging industry. The memory is based on sintering of metallic nanoparticles using an electric current. A low voltage of a few volts is sufficient for the writing of the memory. Because the sintering of nanoparticles is non-reversible, the
