Abstract
An integrated circuit chip includes a rectifier circuit configured to convert an alternating voltage supplied from an antenna into a direct-current voltage, a nonvolatile memory coupled to the rectifier circuit to operate by use of the direct-current voltage, a sensor circuit coupled to the rectifier circuit to operate by use of the direct-current voltage to collect measurement data, and a logic circuit configured to control the nonvolatile memory and the sensor circuit such that an access operation of the nonvolatile memory and a data collecting operation of the sensor circuit are not performed concurrently.
