<p>PURPOSE:To simplify the constitution of a ROM writer, by providing a read part to read out data in a first programmable ROM and a write part to write the data on a second programmable ROM, and designating addresses on them from a control part. CONSTITUTION:The ROM write 10A is constituted of the control part 1, an operation part 5, the read part 2a for a PROM, and the write part 3a for the PROM. The writer is constituted in such a way, and a PROM20 in which the data is written is connected to the read part 2a for the PROM, and a new PROM40 in which no data is written to the write part 3a for the PROM. After components being constituted in such way, the address is inputted to the operation part 5, the addresses are designated on the PROMs 20 and 40, and a read instruction is issued to the PROM20, and a write instruction to the PROM 40, then, they are operated respectively. Therefore, no change-over switch, etc., is required, and the constitution of an equipment can be simplified, and also, only one time of operation is required.</p> |
