TL;DR: This work has focused on defining just the storage node portion of the devices, which utilize the resis-tance change within the film to store information via two dif-ferent stable resistance states, and has attempted to de-termine the properties of such structures.
Abstract: while still retaining a selective switch (transistor or diode) asthe data storage element. Thus for high-density applications,crossbar structures are ideal, whereas for non-volatility, resis-tance-change materials showthe best promise. In orderto rea-lize the fabrication of universal memory elements, it is im-perative to develop a class of materials and structures thatcombine robust processibility, strong scalability, and rapidprogramming speed with non-volatility and low power con-sumption. In our work, we have focused on defining just thestorage node portion of the devices, which utilize the resis-tance change within the film to store information via two dif-ferent stable resistance states. Here, we have attempted to de-termine the properties of such structures and to study themechanisms behind resistance RAM (RRAM) storage. OurTi-doped (0.1 wt %) NiO samples deposited at room temper-ature show favorable node characteristics such as the lowestwrite current reported thus far for a unipolar switching resis-tance-change-based device (ca. 10 lA). In addition, the pro-gramming speed is comparable to the write time of SRAM(10 ns). By combining this node element with an appropriateselect switch, such as a high-performance diode, a thresholddevice, or a two-terminal non-ohmic device, it becomes possi-ble to fabricate high-density universal memory.Indeed, the fabrication of universal memory as the nextgeneration of non-volatile memory is the logical goal for re-search in this field. In comparison to Flash and dynamicRAM (DRAM), which are the current industry standards,next generation memories must combine the non-volatility ofFlash with the high-speed performance of SRAM.

13 Aug 2008TL;DR: In this article, an apparatus and method for cooperative relay in a multiple-antenna wireless communication system based on relay stations (RSs) is provided. But it is not a cooperative relay relay relay system.
Abstract: An apparatus and method for cooperative relay in a multiple-antenna wireless communication system based on relay stations (RSs) are provided. The apparatus includes a serial/parallel converter for dividing data into N number of streams, a channel estimator for calculating a first transmission rate at which a RS performing the cooperative relay can perform decoding and a second transmission rate at which all relay stations performing the cooperative relay can commonly perform decoding, and determining transmission rates for each of the N-number streams, and an adaptive modulation and coding (AMC) unit for encoding and modulating the N-number streams according to their respective transmission rates.

TL;DR: A 2.1 M pixel, 120 frame/s CMOS image sensor with column-parallel delta-sigma (ΔΣ) ADC architecture with second-order ΔΣ ADC improves the conversion speed while reducing the random noise (RN) level as well.
Abstract: This paper presents a 2.1 M pixel, 120 frame/s CMOS image sensor with column-parallel delta-sigma (ΔΣ) ADC architecture. The use of a second-order ΔΣ ADC improves the conversion speed while reducing the random noise (RN) level as well. The ΔΣ ADC employing an inverter-based ΔΣ modulator and a compact decimation filter is accommodated within a fine pixel pitch of 2.25-μm and improves energy efficiency while providing a high frame-rate of 120 frame/s. A prototype image sensor has been fabricated with a 0.13-μm CMOS process. Measurement results show a RN of 2.4 erms- and a dynamic range of 73 dB. The power consumption of the prototype image sensor is only 180 mW. This work achieves the energy efficiency of 1.7 e-·nJ.
