A programmable logic device that is capable of changing the function of only an intended logic element without interfering with other logic elements in operation. The logic elements include a main storing unit operable to store therein first configuration information, a preparatory storing unit operable to store therein second configurations information that is to be transferred to and stored in the main storing unit in dependence on a rewrite permit construction. Each logic element, which the configuration information should not be rewritten, does not rewrite the configuration information. Accordingly, the function of the intended logic element can be changed by rewriting the configuration information in the intended logic element. The function of other logic elements can remain unchanged by not rewriting the configuration information in the logic element. An associated configuration apparatus is also provided. |
