In this paper, we introduce the analog memory fabricated in a 0.35${\mu}{\textrm}{m}$ single poly standard CMOS process. We measured the programming characteristics of the analog memory cell such as linearity, reliability etc. Finally, we found that the characteristics of the programming of the cell depend on the magnitude and the width of the programming pulse, and that the accuracy of the programming within 10mV is feasible under the optimal condition. In order to standardize the characteristics of the cell, we have investigated numbers of cells. Thus we have used a program named Labview and a data acquisition board to accumulate the data related to the programming characteristics automatically.

This study analyzed the impacts of programming characteristics perceived by the consumers of entertainment programs on general programming channels on watching intention and the data of a survey with 360 adult viewers in the capital area. Research questions were verified as follows: First, as a result of multiple regression to analyze the impacts of the factors of programming characteristics perceived by the consumers on their watching intention, setting personal characteristics as a control variable, programming characteristics as an independent variable and watching intention as a dependent variable, the regression model was significant. Thus, the more positive the perceived factors of programming characteristics, the more significant their watching intention improved. Second, the factors of programming characteristics significantly affecting watching intention had greater positive(+) impacts in the following order: Adjacency > substantiality > weight of genre > social evidence > relative advantage > ease of access.

The temperature effects of programming speed and endurance characteristics in p-channel flash memory cell have been investigated. In the case of room temperature, the programming speed of p-channel flash memory by using BTB scheme is faster than that by using CHE scheme. However, endurance characteristics with BTB programming scheme is not better than that with CHE programming scheme. In the case of elevated temperature, CHE programming speed is reduced due the gate current degradation but BTB programming speed is enhanced due to the increasing of gate current. Finally, the endurance characteristics of both schemes are improved due to the reduction of gate oxide traps.

In this paper, the programming characteristics of the multi-bit devices based on SONOS structure are investigated. Our devices have been fabricated by 0.35 $\mu\textrm{m}$ complementary metal-oxide-semiconductor (CMOS) process with LOCOS isolation. In order to achieve the multi-bit operation per cell, charges must be locally frapped in the nitride layer above the channel near the source-drain junction. Programming method is selected by Channel Hot Electron (CUE) injection which is available for localized trap in nitride film. To demonstrate CHE injection, substrate current (Isub) and one-shot programming curve are investigated. The multi-bit operation which stores two-bit per cell is investigated. Also, Hot Hole(HH) injection for fast erasing is used. The fabricated SONOS devices have ultra-thinner gate dielectrics and then have lower programming voltage, simpler process and better scalability compared to any other multi-bit storage Flash memory. Our programming characteristics are shown to be the most promising for the multi-bit flash memory.

It has been reported that programming education has a positive effect on 'improvement of problem solving skills' within the domain of information subject. Improvement of problem solving skills through education programming was confirmed through various variables, such as gender and programming method. This study aims to investigate the proper programming method of each learner by dividing the characteristics of learners according to their characteristics. To achieve our goal, we chose 62 S high school students enrolled in a programming class as the subjects of our study. The results of this study conveyed that project preference and gender can affect the achievement of the individual, whereas programming experience can affect the achievement of the team. This study provides suggestions of how to pursue a programming class according to learner characteristics as well as indicate which characteristics we should take into account.

The purpose in this paper is to provide the theoretical framework of characteristics of programming thinking processes in computational literacy education. That is, we developed the theoretical framework through analyzing novices' cognitive thinking processes, applied it to the real situation about computational literacy problem-solving processes and defined characteristics of the processes. For this purpose, we tried to analyze characteristics of programming thinking processes of novices by using think-aloud method. Also we developed the programming process code about novices' cognitive processes and programming processes, and analyzed the process that novice faced and overcame programming barriers by using qualitative research tool, Nvivo. As a result, we found what characteristics of programming problem-solving processes were and how novices used the thinking skill in the process. This study contributes to understand programming problem-solving processes and provides the criterion to analyze the processes scientifically.

In this paper, we try to explore basic factors that defines easy-to-learn programming language and easy-to-learn development environments for novice students who have not been exposed to computer programming language education. For these purpose, we investigate and analyze computer programming languages that are widely used in industrial environments, and present the summary and analyzed results. From the experimental results, most novice programmers understand computer programming languages in terms of procedural programming languages rather than in terms of functional programming languages or object oriented programming languages. Furthermore, we have found that, for effective education of basic level programming languages, factors of development environments are much more important than factors of programming paradigms that the computer programming languages are based on.

Inthis apper wa analyzed the channel-hot-electron programming characteristics of the single-poly EEPROM with different control gate and drain structures. The single-poly EEPROM uses the p$^{+}$/n$^{+}$-diffusion in the n-well as a control gate instead of the second poly-silicon. The program and erase characteristics of the single-poly EEPROM were verified using the two-dimensional device simulator, MEDICI. The single-poly EEPROM was fabricated using 0.8$\mu$m ASIC CMOS process, and its CHE programming characteristics were measured using HP4155 parameteric analyzer and HP8110 pulse gnerator. Especially we investigated the CHE programming characteristics of the single-poly EEPROM with the p$^{+}$-diffusion or n$^{+}$-diffusion in the n-well as a control gate and the LDD or single-drain structure. The single-poly EEPROM with p$^{+}$-diffusion in the n-well as a control gate and single-drain structure was programmed to about VT$\thickapprox$5V with VDS=6V, VCG=12V(1ms pulse width).th).

There generally exists a large variation in the thereshold voltages of the flash EEPROM cells after they are erased by using th fowler-nordheim tunneling, thereby getting some cells to be overeased. If the overerased cells are programmed with the conventional one-step programming scheme where an 12-13V pulse with the duration of 100.mu.S is applie don the control gate for the programming, they can suffer from the significant degradation of the reliability of the gate oxide. A two-step programming schem, where an 8/12 V pulse with a duration of 50.mu.S for each voltage is applied on the control gate for the programming, has been studied to solve the problem. The experimental results hav eshown that there is little difference in the programming characteristics between those two schemes, whereas the degradation of the gate oxide due to the programming can be significantly reduced with the two-step programming scheme compared to that with the one-step programming scheme. This is possibly because the positive charge stored in the floating gate of the overerased cells is compensate dwith the electrons injected into the floating gate while the 8V pulse is applied on the control gate, which leaves the overerased cells in the normally erased state after the duration of the 8V pulse.

Computational Literacy education is being required in current digital age, but the educational strategy of it is lacking. In traditional education, instructors have been teaching by considering learners' characteristics for effective learning. It is necessary to investigate their characteristics for applying this method to computational literacy education. Therefore, we taught programming that is main area on computational literacy, and analyzed learners' characteristics focused on Felder's learning style and multiple intelligence. That is, we taught 194 university students computational literacy with scratch that was one of the popular educational programming languages, and analyzed the relation among learning style, multiple intelligence and the students' programming performance. Also, we found considerations through comparing students' characteristics with experts' ones.
