摘要： A memory transistor and a select transistor are disposed side by side on a semiconductor substrate between source/drain diffusion layers thereof, with an intermediate diffusion layer interposed therebetween. The memory transistor includes: a gate insulating film having such a thickness as to allow tunneling current to pass therethrough; a floating gate electrode; an interelectrode insulating film; and a control gate electrode. The select transistor includes a gate insulating film and a select gate electrode. Tunneling current, allowing electrons to pass through the gate insulating film under the floating gate electrode, is utilized during the removal and injection of electrons from/into the floating gate electrode. As a result, higher reliability can be attained and rewriting can be performed at a lower volt age. Also, since the select transistor is provided, reading c an also be performed at a lower voltage. Improvement of reliability and rewrite and read operations at respective lower voltages are realized for a nonvolatile semiconductor memory device, in which a memory cell includes a floating gate electrode and a control gate electrode.

A second lower layer control unit controls a conveyance unit, that conveys the medium in a second conveyance section located downstream of the first conveyance section. An upper layer control unit determines whether the medium is at a position where both the first lower layer control unit and the second lower layer control unit engage with conveyance control of the medium, instructs the first lower layer control unit and the second lower layer control unit to operate in synchronization with each other when the medium is at the position, and instructs the second lower layer control unit to operate asynchronously to the first lower layer control unit when the medium is not at the position.

摘要： The protection element of the present invention is constructed of a MOS capacitor composed of a semiconductor substrate, an insulating film formed on the semiconductor substrate and a word line formed on the insulating film. A well region having a conductivity type opposite to that of the semiconductor substrate is formed in a portion of the semiconductor substrate constituting the MOS capacitor. If charge exceeding the breakdown voltage of the insulating film constituting the MOS capacitor is induced in the word line, the induced charge is released into either the semiconductor substrate or the well region depending on whether the induced charge is positive or negative.
