Several emerging nonvolatile memories (NVMs) including phase-change RAM (PCRAM) [1-3], MRAM [4-5], and resistive RAM (RRAM) [6-8] have achieved faster operating speeds than embedded Flash. Among those emerging NVMs, RRAM has advantages in faster write time, a larger resistance-ratio (R-ratio), and smaller write power consumption. However, RRAM cells have(More)
The use of low voltage circuits and power-off mode help to reduce the power consumption of chips. Non-volatile logic (nvLogic) and nonvolatile SRAM (nvSRAM) enable a chip to preserve its key local states and data, while providing faster power-on/off speeds than those available with conventional two-macro schemes. Resistive memory (memristor) devices feature(More)
Mobile systems require high-performance and low-power SoC or 3D-IC chips to perform complex operations, ensure a small form-factor and ensure a long battery life time. A low supply voltage (VDD) is frequently utilized to suppress dynamic power consumption, standby current, and thermal effects in SoC and 3D-IC. Furthermore, lowering the VDD reduces the(More)
