2nTP FAQs

Q: What is 2nTP?

A: 2nTP is a multi-time write block that is based off of Novocell's patented OTP anti-fuse technology.  The 2nTP block gives users the ability to program the block up to 4 times with a limited area increase.

Q: What problems does 2nTP solve?

A: 2nTP gives users a multi-time write ability with the added benifits of OTP security and reliability.  

Q: What are the benefits of using 2nTP?

A:  The 2nTP design bridges the inherant gap between Flash (EEPROM 1,000+ write) Designs and OTP (One Time Write) designs with limited area increase (~60% area savings).

Q: Why would I use 2nTP when I could use multiple OTP blocks?

A: By putting down multiple OTP memories you are repeating circuitry and adding redundancy.  With Novocell's patented antifuse bit cell as the basis of the 2nTP design, we can add multiple antifuse devices without the area increases of multiple blocks.

Q: Are there any additional liability concerns?

A:  The 2nTP design utilizes the NovoBlox SmartBit cell which has been extensively qualified and tested.  Any process or geometry in which NovoBlox OTP technology is qualified; the 2nTP design will have the same functionality and reliability.

Q: How can you get such an area savings with 2nTP?

A:  Due to the unique NovoBlox SmartBit cell design which has an included breakdown detector and voltage generator,  additional antifuse devices can be added to individual cells without significant area increases.
