  • Publication number: 20210025724
    Abstract: The present disclosure relates to an apparatus and methods of estimating a traffic volume of moving objects. In particular, the present disclosure estimates the traffic volume based on amounts of traffic volume of the moving objects observed at observation points based on a routing matrix and a visitor matrix. The routing matrix indicates whether moving objects that pass through specific waypoints are to be observed at an observation point. The visitor matrix indicates whether a moving object departing or arriving at the observation point. The present disclosure enables estimating a traffic volume of moving objects on various routes based on observed data with errors in data and varying lengths in observation periods.

    Abstract: According to one embodiment, a semiconductor memory device includes: a word line; a first memory cell; a first circuit; and a second circuit. The first memory cell is connected to the word line. The first circuit generates a first voltage having a waveform including a first time period during which a voltage value increases with time and a second time period during which the voltage value decreases with time, and applies the generated first voltage to the word line. The second circuit measures first time from a first timing when a state of the first memory cell changes according to the first voltage to a second timing when the state of the first memory cell changes according to the first voltage after the first timing. The second circuit determines first data stored in the first memory cell on the basis of the measured first time.
