摘要：
A memory system including a circuit for switching control of a read-only memory and a random-access memory to allocate addresses thereto. The addresses are switched between the read-only memory and the random-access memory by selecting a mode in which the read-only memory is operated when reading therefrom and the random-access memory is operated when writing thereinto, and a mode in which the random-access memory is operated when reading therefrom and writing thereinto.
