Embedded Logic NVM Technology
In order to meet a variety of applications requiring memory on demand, particularly in 0.35um processes, we provide three kinds of logic-based Non-Volatile Memory (NVM). They are (1) Yield Microelectronics Corporation’s (YMC) 3.3V MTP (Multi-Time-Programing) NVM IP; (2) eMemory’s 5V OTP (One-Time-Programing) NVM IP; and (3) Nuvotons Own Poly e-Fuse IP for Trimming.
| Application | Target Product | Function | 0.35um | MVN IP |
|---|---|---|---|---|
| Trimming | LCD Driver, LED Driver, Touch Panel, Power IC STB Control | Fuse Like | 5V/40V/UHV or BCD | eMemory 5V OTPNTC Poly e-Fuse |
| Parameter Setting | LCD, LED, Battery Pack Protection | Status Parameter | 5V/40V/HV or BCD | eMemory 5V OTP |
| Encryption | LCD, STB, Smart Card | Security Confirm Code | 5V/40V/HV or BCD | eMemory 5V OTP |
| Function Selection | SoC product Function selector | SoC Function Control | 3.3V/5V Logic | YMC 3.3V MTP |
| Identification Setting | Product ID, TagIC < 13.5MHz | ID Code | 3.3V/5V Logic | YMC 3.3V MTP |
| Code Storage | 4/8 bits MCU | Program, Data Storage | 3.3V/5V Logic | YMC 3.3V MTP |
YMC 3.3V MTP NVM IP
Nuvoton Technology Corp. in cooperation with YMC, provides a 3.3V MTP NVM IP on 0.35um 3.3V/5V logic process that enables customers to run the process with YMC IP without additional mask and process costs. The NVM IP types YMC provides (1) EEPROM (2) Flash (3) MTP. The IP memory density ranges from 256x8 bits to 16Kx16 bits. This process has been widely used for Microcontroller (MCU) products.
eMemory 5V OTP NVM IP
Nuvoton Technology develops power management and high-voltage process. In 0.35um technology, it provides modular manufacturing with integrated eMemory 5V OTP NVM IP for customers in fields such as power management with embedded memory technologies. Nuvoton also enables customers to run Nuvoton’s 0.35um BCD process with eMemory 5V OTP NVM IP without additional mask and process costs.
Nuvoton Poly e-Fuse IP
Nuvoton Technology offers proprietary Poly Electrical Fuse (Poly e-Fuse) IP in the 0.35um BCD and 0.6um CDMOS/UHV processes. Poly e-Fuse IP is used for analog and power management IC Trimming with lower cost than traditional PAD E-fuse solutions. Trimming using this IP may allow the customer to skip Final Test (FT) for more cost savings. Compared to Laser fuses, Nuvoton Poly e-Fuse IP saves trimming costs and enhances yield.
