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 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.
