Low-power charge-sharing ROM using dummy bit lines
No full textA shared-capacitor charge-sharing ROM (SCCS-ROM) is proposed to lower the bit line swing voltage by using charge-sharing. It uses only three capacitors for the charge-sharing and it implements the capacitors with dummy bit lines. This not only increases noise immunity but also reduces power. The SCCS-ROM achieves 8.4% power reduction.This work was supported by KOSEF through the MICROS at KAIST, Korea
A low-power charge-recycling ROM architecture
No full textThis paper describes a newly proposed low-power charge-recycling read-only memory (CR-ROM) architecture. The CR-ROM reduces the power consumption in bit lines, word lines, and precharge lines by recycling the previously used charge. In the proposed CR-ROM, bit-line swing voltage is lowered by the charge recycling between bit lines. When N bit lines recycle their charges, the swing voltage and the power of the bit lines become 1/N and 1/N-2 compared to the conventional ROMs, respectively. As the number of N increases, the power saving in bit lines becomes salient. Also, power consumption in word lines and precharge lines can be reduced theoretically to half by the proposed charge-recycling techniques. The simulation results show that the CR-ROM consumes 60%similar to85% of the conventional low-power ROMs with 1 K x 32 b. A CR-ROM with 32 kb was implemented in a 0.35-mum CMOS process. The power dissipation is 6.60 mW at 100 MHz with 3.3 V and the maximum operating clock frequency is 150 MHz
A low-power ROM using charge recycling and charge sharing techniques
No full textIn a memory, most power is dissipated in high-capacitive lines such as predecoder lines, wordlines, and bitlines. To reduce the power dissipation in these high-capacitive lines, this paper proposes three techniques using charge recycling and charge sharing. The first is the charge recycling predecoder (CRPD) , the second is the charge recycling wordline decoder (CRWD), and the last one is the charge sharing bitline (CSBL) for a ROM. The CRPD and the CRVM recycle the previously used charge in predecoder lines and wordlines. Theoretically, the power consumption in predecoder lines and wordlines are reduced to a half. The CSBL reduces the swing voltage in the ROM bitlines to very small voltage using a charge sharing technique with three small capacitors. The CSBL can significantly reduce the power dissipation in ROM bitlines. The CRPD, the CRWD, and the CSBL consume 82%, 72%, and 64%, respectively, of the power of previous ROM designs. A charge recycling and charge sharing ROM (CRCS-ROM) with the CRPD, the CRWD, and the CSBL is implemented. A CRCS-ROM with 8K x 16 bits was fabricated in a 0.35-mum CMOS process. The CRCS-ROM consumes 8.63 mW at 100 MHz with 3.3 V. The chip core area is 0.51 mm(2)

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
