Overview and future challenges of Floating Body RAM (FBRAM) technology for 32nm technology node and beyond

Floating body cell (FBC) is a one-transistor memory cell on SOI substrate, which aims high density embedded memory on SOC. In order to verify this memory cell technology, a 128 Mb floating body RAM (FBRAM) with FBC has been designed and successfully developed. The memory cell design and the experimental results, including single cell (1Cell/Bit) operation, are reviewed. Based on the experimental results, the scalability of FBC is also discussed.
