Title: Method of internet radio broadcasting service using the mobile station
Inventor: JUNG SUN HO
IPC: H04W4/18
Filed: 2002-04-16
Abstract: PURPOSE: An Internet radio broadcasting method using a wireless communication terminal is provided to service Internet radio contents, provided by and broadcasted in various Internet radio broadcasting stations, to the wireless communication terminal. CONSTITUTION: An Internet radio broadcasting station server confirmed as a member transmits Internet radio broadcasting contents as a broadcasting stream packet to a wireless communication company server(303). The wireless communication company server buffers and processes the broadcasting stream packet of the Internet radio broadcasting contents received from the Internet radio broadcasting station server, and packetizes the broadcasting stream packet into a data size suitable for being transmitted to the wireless communication terminal, and stores and manages the packetized broadcasting stream packet in a database(304). The wireless communication company server lists information about the Internet radio broadcasting contents(304), and transmits an Internet radio broadcasting list to a wireless communication terminal(305). A user of the wireless communication terminal retrieves desired Internet radio broadcasting contents from the Internet radio broadcasting list provided to the wireless communication terminal(306). The user of the wireless communication terminal selects the desired Internet radio broadcasting contents(307), and requests the wireless communication company server to transmit the corresponding Internet radio broadcasting contents(309). The wireless communication company server receives the request of the transmission of the Internet radio broadcasting contents, retrieves the database, extracts the packetized Internet radio broadcasting contents, and transmits the extracted Internet radio broadcasting contents to the wireless communication terminal(310). The wireless communication terminal receives the Internet radio broadcasting contents, depacketizes the received Internet radio broadcasting contents, buffers and decodes the depacketized Internet radio broadcasting contents, and converts the depacketized Internet radio broadcasting contents into a service band(311). The wireless communication terminal amplifies the converted Internet radio broadcasting contents, and outputs the amplified Internet radio broadcasting contents(311).

Title: Semiconductor integrated circuit with memory redundancy circuit
Inventor: HARADA MASASHIGE
IPC: G11C29/42
Filed: 2002-06-21
Abstract: PURPOSE: A semiconductor device is provided to correct errors such as soft errors and hardware defects without the need for an increase in area and without causing more power to be consumed. CONSTITUTION: A semiconductor device includes a plurality of memory blocks. Each block comprises a memory array, a latch type sense amplifier circuit(CSA), and a Y switch circuit(CYS). The memory array is comprised of memory columns A and memory columns B. The memory columns A and B are allocated to different addresses. For example, assuming that there is one parity bit in every 10-bit address and adjacent memory cells on a word line are allocated to an address, if one of the neighboring memory cells, which share the allocated parity bit, has an error, the error cannot be repaired. On the other hand, if adjacent memory cells are allocated to different addresses, each having its own parity bit, then even if one of the adjacent memory cells has an error, the error is repaired. Since a soft error is likely to occur in an adjacent memory cell, it is useful to allocate a different address to the adjacent column.
