Overview

P2ROM™(Production Programmed ROM) is programmed at LAPIS Semiconductor's facility with the customer's data, then shipped to the customer.

It features short lead time, eliminates customer stock, reducing programming costs, and eliminates mask charges.

Features

Features1
High quality and stable supply

Upstream processing for P2ROM™is performed at two domestic locations (Miyagi and Hamamatsu), while assembly is conducted at Miyazaki and partner locations, and also programming, sorting, and testing are conducted at Miyazaki.

The production system ensures the same level of quality and reliability.

In addition, multiple locations provide the necessary framework to flexibly respond to sudden demands.

 
Features2
Short lead time

LAPIS Semiconductor first prepares unprogrammed memory (ATP banks) for each type of package and density required, then programs and tests them once customer data is received.

This cuts down on lead time significantly compared with Mask ROM, ensuring flexible response to sudden demands while reducing the customer's opportunity losses.

Features3
Stock-free

Since LAPIS Semiconductor prepares the unprogrammed memory (ATP banks), the customer does not need to store it unlike Flash or OTP memory.

In addition to reducing costs, inventory management and control, such as quantity checks and maintenance, are eliminated.

Features4
No additional programming costs / No mask charging

Since P2ROM™ is the programmed and delivered product, the arrangement of program is unnecessary unlike Flash memory. Compared with the case where the Flash memory is programmed by the outside order, reduction of programming cost is possible.

Moreover, since the purchase of facilities and start and maintenance management of production process required when programming in the customer's production process are unnecessary, P2ROM™contributes to all-around cost reduction.

Costs required for coding mask ROMs are not required, reducing expenses significantly.
