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.
