<P>PROBLEM TO BE SOLVED: To provide a data writing device capable of writing data written in an actually-used system also into a back-up system with a high degree of precision and at high speed, and a base station to which the data writing device is applied. <P>SOLUTION: The base station includes a call processing control part of the redundant configuration that transfers data more than twice faster than the address, and writes data in a memory from a CPU. The call processing control part branches and detects an address signal transferred from an actually-used CPU to an actually-used memory, reads out the data written in the actually-used memory based on the detected address through the actually-used CPU, and instructs a back-up CPU to write the read out data to the same address of a back-up memory as the detected address. <P>COPYRIGHT: (C)2009,JPO&INPIT |
