摘要： A charge storage layer interposed between a memory gate electrode and a semiconductor substrate is formed shorter than a gate length of the memory gate electrode or a length of insulating films so as to make the overlapping amount of the charge storage layer and a source region to be less than 40 nm. Therefore, in the write state, since the movement in the transverse direction of the electrons and the holes locally existing in the charge storage layer decreases, the variation of the threshold voltage when holding a high temperature can be reduced. In addition, the effective channel length is made to be 30 nm or less so as to reduce an apparent amount of holes so that coupling of the electrons with the holes in the charge storage layer decreases; therefore, the variation of the threshold voltage when holding at room temperature can be reduced.
摘要翻译：插入在存储栅电极和半导体衬底之间的电荷存储层形成为比存储栅电极的栅极长度或绝缘膜的长度短，以使电荷存储层和源极区域的重叠量成为小于40nm。因此，在写入状态下，由于在电荷存储层中局部存在的电子和空穴的横向的移动减少，因此可以降低保持高温时的阈值电压的变化。此外，有效沟道长度为30nm以下，以减少空穴的表观量，使得电子与电荷存储层中的空穴的耦合减小; 因此，可以降低在室温下保持时的阈值电压的变化。

摘要： A method for controlling a test for an ATM exchange in which a number of test cell generating devices to be activated is limited in association with a load applied to a central processing device so that the test is preformed without occurrence of congestion. The test is performed by using test cells transmitted from a plurality of test cell generating devices provided in the exchange. A load applied to the central processing device is measured, and a number of test cell generating devices to be used is calculated so that the measured load is maintained below a previously set limit value. The test for the exchange is performed by concurrently using the calculated number of test cell generating devices.

摘要： A push-to-talk data transmission device that creates and manages groups of participating terminals dynamically. A PoC data transmission device is deployed to support push-to-talk sessions in a prescribed area. This device has a data transmitter that broadcasts a group profile repetitively in the prescribed area. The group profile is a set of parameters that prompt terminals in the prescribed area to send back their respective unique identifiers to join a push-to-talk session. A counter in the PoC data transmission device counts the number of responses returned from the terminals, and the data transmitter broadcasts a new group profile if the number of responses has reached a predetermined threshold.
