ABSTRACT:
A security module for a radio telephone prevents a KEY code stored in a non-volatile memory from being read out for illicit use. The security module deletes the KEY code stored in the memory when accessed from the outside. Hence, although a KEY code can be written to the memory or the operation of the memory can be tested from the outside, the KEY code is prevented from being read out by an unauthorized person.
