  • Patent number: 7907451
    Abstract: The disclosure of this application enhances the data writing speed of an electrically erasable and writable semiconductor memory. In a semiconductor storage device of this application, at a time of writing data, when a positive voltage lower than a voltage at control gate 30 is applied to potential control gate 28 formed inside tunnel oxide film 360 between p channel 22 of a transistor and floating gate 32, a potential barrier between p channel 22 of the transistor and floating gate 32 is lowered, and a time required for storing an electron in floating gate 30 is reduced. After data is stored, when 0 V or a negative voltage is applied to the potential control gate, a potential barrier for an electron moving from the floating gate to the channel of the transistor increases, thereby preventing erasure of data.

  • Patent number: 7454780
    Abstract: This invention relates to a service providing system and a service providing method for allowing users to receive a service from a service server without having to submit their security-critical information to that server. A CE device 1 requests provision of the service by transmitting authentication information such as a device ID to a surrogate authentication server 2. The surrogate authentication server 2 authenticates the CE device 1 based on the authentication information and transmits a result of the authentication to the service server 3. In turn, the service server 3 provides the CE device 1 with the requested service based on the result of the authentication received from the surrogate authentication server 2. The CE device 1 then uses the service provided by the service server 3. This system can be applied advantageously to network-based marketing systems.
