Abstract: According to one embodiment, a semiconductor memory device includes a memory cell array, a bit line, a source line, and a sense circuit. The memory cell array includes memory strings which include memory cells connected in series and stacked above a semiconductor substrate. The bit line is coupled to one of the memory strings and is capable of transferring data. The source line is coupled to one of the memory strings. When data is read, a read current flows from a bit line into the source line. The sense circuit is coupled to the bit line and senses read data. An operation timing of the sense circuit is determined on the basis of a current flowing through the source line.

Abstract: A power supply circuit drives circuits having different numbers of series-connected LEDs without changing a circuit constant or a component. An LED series circuit is connected to a power converter circuit of a power supply circuit. The power converter circuit is controlled by a control arithmetic circuit, and supplies a constant current to the LED series circuit. A voltage detection circuit detects a voltage applied to the LED series circuit. The control arithmetic circuit checks whether the LED series circuit has 40 LEDs or 20 LEDs, based on the voltage detected by the voltage detection circuit. The control arithmetic circuit holds a constant-current value table for 40 LEDs and a constant-current value table for 20 LEDs. In accordance with the detected voltage, the control arithmetic circuit selects one constant-current value table, and controls the power converter circuit based on the constant-current value table selected.

Abstract: A memory cell array has plural memory strings arranged therein, each of which including a plurality of electrically-rewritable memory transistors and selection transistors. Each memory string includes a body semiconductor layer including four or more columnar portions, and a joining portion formed to join the lower ends thereof. An electric charge storage layer is formed to surround a side surface of the columnar portions. A first conductive layer is formed to surround a side surface of the columnar portions as well as the electric charge storage layer. A plurality of second conductive layers are formed on side surfaces of the joining portion via an insulation film, and function as control electrodes of a plurality of back-gate transistors formed at a respective one of the joining portions.

Abstract: This invention provides a coin depositing and dispensing machine capable of clearly specifying whether each coin dispensed into the same coin dispensing port is a coin to be paid or rejected coin, and preventing the coins from being mistakenly mishandled. Light emitting unit capable of emitting light of different colors is disposed in the vicinity of the coin dispensing port. The light emitting unit emits a green light if the coin dispensed into the coin dispensing port is a coin to be paid, and emits a red light if the dispensed coin is a rejected coin. The light emitting unit irradiates light to the whole coin dispensing port and the coins themselves in the coin dispensing port. When the coins are taken out from the coin dispensing port, it can be recognized whether the coin is a coin to be paid or rejected coin.
