  • Abstract
    A novel partially-depleted (PD) SONOS FinFET is demonstrated for unified function of a high speed capacitorless IT-DRAM and non-volatile memory (NVM). A floating body and O/N/O layer are combined in a single FinFET to provide multi-functional unified-RAM (URAM) operation. The fabricated URAM shows a VT window of 3 V with a retention time exceeding 10 years for NVM operation and a sensing margin of 9 muA with a program/erase time of 10 nsec for IT-DRAM operation in a single memory cell transistor.
