P2ROM ADVANCED TECHNOLOGY
P2ROM stands for Production Programmed ROM.
This exclusive LAPIS Semiconductor 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.
