<p>PURPOSE:To decrease the frequency of writing and improve a life and reliability by converting absolute addresses which are large in write frequency and absolute addresses which are small in write frequency in order. CONSTITUTION:An instruction decoder part 10 specifies a write storage area (relative address) to an address conversion part 2 from outside, sets absolute addresses corresponding to the write storage area in an address decoder part 6, and read data out of an address where writing is to be performed currently; and then the data are stored in a primary storage part 4 for comparison and the absolute address which is currently read is stored in an address storage part 5. Then data are read out in order from a next address (absolute address) which is read and the data in the temporary storage part 4 for comparison are compared with data in a data latch 8. Consequently, when the data match each other, the absolute address is converted.</p> |
