<p>PURPOSE:To enable a storing of write-data names correspondent to the write data in a PROM (programmable read only memory) IC by providing a circuit dedicated to the write/read control to the write-data-name storing memory cell. CONSTITUTION:The write-data-name storing memory cell 7 is provided in the PROM memory cell 3. The writing in and reading out from the cell 7 are controlled through the decoder and the selecting circuit 8 that are dedicated to the cell 7. With this configuration, there is no necessity of writing names by imprinting and reading them out, and thus the PROM IC is made able to store the write names correspondent to the write data which are also able to be read out.</p> |
