摘要： A semiconductor memory device includes first and second MOS transistors. The first MOS transistor is formed on a region enclosed by a first element isolating region and includes a first gate insulating film and a first gate electrode. The second MOS transistor is formed on a region enclosed by a second element isolating region and includes a second gate insulating film and a second gate electrode. The upper part of the first and second element isolating regions project from a semiconductor substrate and their corners are curved. The width from the position where the first element isolating region contacts the first gate insulating film to the top surface end of the first element isolating region is equal to the width from the position where the second element isolating region contacts the second gate insulating film to the top surface end of the second element isolating region.

摘要： A NAND column has memory cell transistors connected in series by a current passage. Word line drive circuits supply a low voltage to a word lines. A potential supply circuit supplies a high potential higher than the low potential, to a semiconductor region in which the memory cell transistors are formed, to delete contents stored in the memory cell transistors. In deletion verification which verifies that the contents stored in the memory cell transistors have been deleted, a read is executed on each of the word lines. In the read, the word line drive circuit provides the selected one of the word lines with a determination potential used to determine whether or not the contents have been deleted, while providing the other non-selected word lines with a read potential higher than the determination potential.

摘要： Terminals and base stations belonging to service areas 100 to 102 of plural radio operators periodically measure a radio-link quality and an availability ratio of a radio link to notify them to a radio-resource management server 40. The server 40 alters a frequency of the base station, and a transmitted-power quantity of the base station and the terminal based on these measured results to improve the radio-link quality, and reduces interference with a neighboring radio system. When a load is concentrated on a network of a specific radio operator, an instruction of handover is given to the terminal from the server 40 to realize a load distribution within the radio operator, and between the radio operators. When the server 40 detects excessive radio interference between the radio operators, it notifies occurrence of a fault, an interference quantity, a quantity of the transmitted power that the base station should attenuate, and the frequency that the base station should alter to the above radio operator that becomes an interference source.

摘要： The radio resource management server 1 receives radio link quality information measured by the radio base station 2 and radio link quality information measured by the radio base station 3 and thus detects the occurrence of interference. Upon the occurrence of the interference, the transmission power of the radio base station causing the occurrence of interference is controllably reduced to suppress the interference. In the method of controllably varying the transmission power of a radio base station, depending on the number of radio terminals or traffic volume, oscillation of a service area occurs. However, according to the present invention, the transmission power is changed on the occurrence of interference, without depending on the number of radio terminals or traffic volume, so that the area oscillation does not occur after the transmission power has been once stabilized.
