Information services are provided via an over-the-air television broadcasting system that is segmented into a plurality of cells. Each cell includes one or more transmitting facilities for transmitting service information and mapping information. The mapping information includes adjacent cell information enabling mobile receiver units to transition between cells in order to continue receipt of service information without requiring communication from the receiver unit to the service provider. The transmitting facilities of adjacent cells may operate on the same television channel and/or on different television channels, typically chosen from a frequency set allocated to a given service provider. The service information may include different content in different cells, such as local content specific to each cell. The service information may be provided from one or more content servers in communication with the transmitting facilities.

A semiconductor integrated circuit has a memory which can enter active state or standby state, and the memory has voltage generation circuits for bit lines and source lines with which memory cells are connected. The voltage generation circuits make the potential of the bit lines and the potential of the source lines equal to each other in response to an instruction to transition from active state to standby state. The voltage generation circuits produce a potential difference between the bit lines and the source lines in response to an instruction to transition from standby state to active state. In standby state, the potential of the bit lines and that of the source lines are equal to each other. Therefore, sub-threshold leakage does not occur between the source and drain of each memory cell. In active state, the source line potential is not varied.

There are provided an IP telephone system and method for establishing a connection to the IP network 4 via a public line network and performing talking by transmitting/receiving IP packet data into which audio data has been converted. In a location server 3 arranged on a PSTN 5 or the IP network 4, a public line telephone number and an IP telephone number which are attached to the line connected to a telephone terminal 1a and a terminal identifier identifying the telephone terminal 1a are registered while correlating them to each other. When an IVR 8 is called, the public line telephone number, the IP telephone number of the telephone terminal 1a and/or the terminal identifier is acquired from the telephone terminal 1a and the registration content in the location server 3 is modified via a registrar system 7.

An IP terminal 1 at a transmitting end has a copying unit 111 for copying packet data to be transmitted; an address setting unit 112 for adding unique address information to the respective copied packet data having the same contents; and a transmitting unit 113 for outputting, based on the address information, the copied packet data to different paths 1, 2 on an IP network 3. An IP terminal 5 has a selecting unit 523 for selecting and acquiring the first arriving packet data of the copied packet data having the same contents. In this way, for a data communication in a communication network such as Internet, a plurality of communication paths are used in a packet network, thereby reducing packet jitter and loss at the receiving end and providing a real time service having substantially the same quality as in a line exchanging network.

The present invention relates to a booster circuit of a non-volatile memory requiring a plus or minus high voltage equal to or higher than a power-supply voltage. The present invention can generate a high voltage of approximately 12 V even at a low power-supply voltage equal to or lower than 3 V and generate not only a plus high voltage but also a minus high voltage by the same circuit. Also, by combining a body-controlled type parallel charge pump, which is a booster circuit according to the present invention, with a serial-type charge pump, two types of high voltages can be efficiently generated and a reduction in chip areas can be achieved.
