Abstract :
Recently, a nonvolatile memory embedded in microcontrollers has been required to have 100 ns access time at 2.0 V for mobile information terminals operating with a re-chargeable battery. To achieve this, this paper proposes new architecture for a ferroelectric nonvolatile memory (FeRAM) comprised of (a) Bitline-Driven Read Scheme and (b) Non-Relaxation Reference Cell for high speed and low voltage operation respectively. Using this architecture, a FeRAM with one transistor and one capacitor per bit (1T/1C) cell can have a performance of 100 ns access time at 2.0 V.
