Abstract

PURPOSE: To extend memory using life and to effectively utilize a memory resource by providing this data writing device with a deciding means for deciding the using life of the memory and an address changing means for setting up a new write address in write data by referring the stored contents of a write address control means.
CONSTITUTION: The data writing device is provided with the deciding means 4 for checking whether data written in the memory 1 have normally been written or not and the address changing means 5 for setting up a new write address in write data by referring the stored contents of the write address control means 2. When the limit of the using life is decided, a new write address out of excessive capacity is set up in the write data by referring the stored contents of the means 2. Thereby, data to be frequently written are stored in another area. Thus, the memory using life can be extended and the memory resource can be effectively utilized.
