Floating-gate MOS devices using thin tunnel oxide are becoming an acceptable standard in electrically erasable nonvolatile memory. Theoretical and experimental analysis of WRITE~ERASE characteristics for this type of memory cell are presented. A simplified device model is given based on the concept of coupling ratios. The WRITE operation is adequately(More)
Biliary cholesterol nucleates primarily from phospholipid vesicles. In this study, we investigated the mode of nucleation of micellar cholesterol. Ten biles (four human and six model) were examined. The vesicular and micellar fractions of each bile were separated by gel chromatography. The whole biles and their isolated carriers were incubated at 37 degrees(More)
A 63nm Twin Flash memory cell with a size of 0.0225 mum<sup>2</sup> / 2 (4) bits is presented. The cell is proposed for data Flash products with 4 to 16 Gbit densities. To achieve small cell areas, a buried bit line and an aggressive gate length of ~100 nm are the key features of this 63nm Twin Flash cell. The cell is well capable of 2 and 4 bit operation.
In ulcerative colitis the incidence of adenocarcinoma of the small bowel is higher than in the general population. More than 100 cases of carcinoma of the small bowel have been reported in patients with Crohn's disease of the same segment. However, obstructive carcinoma of the small bowel as the first manifestation of Crohn's disease has seldom been(More)
Obturator hernia is rare and is usually discovered by chance at operation or autopsy. In certain cases obturator hernia may cause sliding and strangulation of abdominal viscera inside the hernial sac, presenting clinically as bowel obstruction. An 83-year-old woman with signs of bowel obstruction was operated after 48 hours of conservative treatment and a(More)
With the exponential growth of digital consumer markets of digital cameras, feature phones, PDAs, personal computers, and portable digital audio/video players, there is high demand for ultrahigh density data storage flash. As the flash density increases to giga-bits (Gb), the critical dimensions are scaling down to sub-90nm. It is commonly understood that(More)
