P2ROM stands for Production Programmed ROM. This

exclusive Oki technology utilizes factory test equipment for

programming the customers code into the P2ROM prior to final
production testing. Advancements in this technology allows
production costs to be equivalent to MASKROM and has many

technologies, which include the following;

· Short lead time, since the P2ROM is programmed at the final

36 Vcc
stage of the production process, a large P2ROM inventory
"bank system" of un-programmed packaged products are
maintained to provide an aggressive lead-time and minimize
liability as a custom product.
· No mask charge, since P2ROMs do not utilize a custom
mask for storing customer code, no mask charges apply.
· No additional programming charge, unlike Flash and OTP that require additional programming and handling
costs, the P2ROM already has the code loaded at the factory with minimal effect on the production throughput.
The cost is included in the unit price.
· Custom Marking is available at no additional charge.
