P2ROM ADVANCED TECHNOLOGY

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

advantages and added benefits over the other non-volatile

technologies, which include the following;

·

Short lead time,

since the P2ROM is programmed at the final 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.

·

Pin Compatible with Mask ROM

and some FLASH products.
