Abstract

A terahertz image measurement device includes a terahertz detection sensor, a magnetic field generating unit, and a measurement control unit. The sensor detects near-field light of terahertz light emitted from a sample. The magnetic field generating unit has a coil disposed around the sample and the sensor, and wound to surround the optical axis of terahertz light irradiated on the sensor, and applies to the sensor a magnetic field generated by allowing an electric current to flow through the coil. The measurement control unit changes a value of the electric current flowing through the coil, sets a strength of the magnetic field to a magnetic field value for which a detection signal level of the terahertz light detected by the sensor increases prominently, and allows the magnetic field value to conform to a specific frequency of the terahertz light.

Abstract

In order to write data at higher speeds and to suppress degradation of non-volatile memory, write data is stored to ReRAM when the page utilization rate R is less than a threshold Rth1 and when the write data is high-frequency rewrite data. Further, when the empty capacity Semp2 of the ReRAM is less than threshold value Sth (step S110), if the ReRAM data is low-frequency rewrite data and the page utilization ratio R when the target data is stored in flash memory (22) is greater than or equal to a threshold value Rth3 (steps S120, S130), data in a logical sector contained in N logical page addresses stored in a transfer list is read from ReRAM and written to flash memory (steps S140-S160). By this means, it is possible to write data at higher speeds and to suppress degradation of flash memory.
