Toshiba Develops World's First Multi-level-cell Structure MROM cell
Toshiba Corporation today announced that the development of the world's first MROM cell to offer improved cell current characteristics without any increase in cell size. This advance was achieved by adopting a multi-level-cell structure, which also secures high speed operation. Details will be presented on June 14 at the 2013 Symposia on VLSI Technology and Circuits, held in Kyoto, Japan, June 11-14, 2013.
MROM's main role is to store the boot loader or firmware. The density of MROM implemented is SoC for such digital applications as smartphones and tablet PCs is increasing year by year, and in order to improve access time it is necessary to halve the MROM cell area with every generation.
