P2ROM stands for Production Programmed ROM. This
exclusive LAPIS Semiconductor’s 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.
