Abstract :
Technologies and improved performance of the floating body RAM are demonstrated. Reducing SOI thickness to 43nm, a 16Mb chip yield of 68% has been obtained. Device simulation proves that the floating body cell is scalable to the 32nm node keeping signal margin (threshold voltage difference) and data retention time constant
