Abstract: An on-vehicle multimedia device to be operated by software 16 including an application module group 18 having a plurality of application modules 19 that realizes their respective different functions and an application control module 17 for controlling each of the application modules 19, characterized by the device comprising external hardware which inputs and outputs data to be processed by the software.

Abstract: A redundancy determination circuit receiving an address signal from an address bus outputs a replacement signal when a set address matches the received address. A multiplexer activates any spare activation signal line that activates respective redundant memory arrays provided in the row direction and column direction in a memory bank at a predetermined timing. The redundancy determination circuit can set the address to use a redundant memory array in either the row direction or the column direction. Therefore, the number of redundancy determination circuits can be reduced.

Abstract: A repair analysis circuit for redundancy, a redundant method for repairing a redundant, and a semiconductor device that can shorten time for testing defective memory cells, that eliminate the need of failure memories having a huge capacity for storing defective bits to make the testing apparatus inexpensive, and that easily cope with increase and decrease in IO numbers. A large number of IO outputs MOUT are collectively compared with a specified expected value, and as a result resultant judgment information DOUT is outputted to an error information acquiring device 22, and an analyzing device 23 reads table information sequentially from each block to obtain replacing data, and the replacing data are outputted serially to the external tester through the external I/F circuit 24. The redundant memory cell 4a itself can be made to compare with a specified expected value in the same manner as other memory cells 4 or the like.
