ABSTRACT:
The present invention provides an excellent car telephone apparatus which can erase the contents of a memory without dismounting the memory from the car telephone apparatus, i.e., with the memory being mounted in the apparatus, and which also can rewrite the contents of the memory by externally transferring modification data. The car telephone apparatus comprises an electrically erasable and rewritable, nonvolatile memory chip, a control means for controlling the erasing/rewriting operation of the memory chip, a means for transferring and collating external writing data, and a means for externally commanding a series of these control operations.
