Flexible, organic flash memory on tap at the University of Tokyo


If the University of Tokyo has its way, we could be seeing an onslaught of flexible computing devices sooner than you think! Earlier this year the school made some noise with its stretchable OLED prototype and now a research group led by Takeo Someya and Tsuyoshi Sekitani has developed a non-volatile, flexible organic flash memory that may someday be used for large-area sensors, electronic paper devices, and non-volatile memory. Using a polyethylene naphthalate (PEN) resin sheet arrayed with memory cells, the memory can be bent until its curvature radius reaches 6mm without causing mechanical or electrical degradation. As it stands now, the device has a memory retention time of one day -- but the team maintains that this can be "drastically improved by reducing the size of the element and employing an SAM with a long molecular length." Piece of cake, right?
