P2ROM ADVANCED TECHNOLOGY
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.
