Provided are an apparatus and a method of managing a reconfiguration data
memory. A space for a memory that stores configuration data used for
reconfiguration of a target system is not provided in the target system.
Instead the configuration data is stored in a separate server and, if
required, the configuration data is transmitted to the target system
through an Internet. Data that should be preserved after the
reconfiguration among data contents stored in SoC internal and external
memories of the target system is transferred to the server. The emptied
space of the SoC internal and external memories is used as a
configuration memory. After the reconfiguration, the preservation data is
returned to its original position in the memories.
