    摘要: The precharge circuit is provided for precharging, before programming the data, the voltage of the source line ARVSS commonly connected to the memory cells provided in the same sector. The voltage of the source line ARVSS of the memory cell MC is precharged before programming the data, and the voltage of the source line ARVSS of the memory cell MC is not lowered at the time of programming the data, even if the data programming period is shortened. It is thus possible to prevent the leak current during the programming and program the data into the memory cell MC optimally.

    摘要: When a key is inserted into a key hole of a lock, magnetism creating means creates a magnetic flux corresponding to a predetermined magnetic code set in the key. Magnetism detecting means detects the magnetic flux and outputs a signal representing the detected magnetic flux. Decision means compares the signal value with a predetermined value, and outputs an agreement signal when the two values are the same. Driving means enables at least unlocking by key operation in response to the agreement signal. The magnetism detecting means outputs, as the above signal, a voltage corresponding to the magnitude of the detected magnetic flux or pulses having a frequency corresponding to same. At least one of material, dimensions, and thickness of the magnetic element determines the predetermined magnetic code. Further, an unlocking mechanism has a magnetic actuator which unlocks the lock by coupling the lock with unlocking means via a cam in response to the agreement signal.
