PROMISE NVM CDR Milestone Successfully Reached
Promise – september 23, 2022
Imec announce the achievement of CDR completion for the embedded NVM IP. The IP is effectively designed from scratch using SONOS embedded Non-Volatile Memory. The NVM is a highly sophisticated IP containing numerous innovations at several levels of the design. Data integrity is a key goal of the design. This includes ECC features and self-calibration for the READ function over the IC’s lifetime. The verification of the IP was just as challenging as the design itself and took several months. The complexity was so high that the CDR process took four lengthy review sessions.
The key parameters of the NVM IP design are given below:
| Size | 21.15 mm2 in 180nm technology |
| Banks | 2 (one can be configured for mirroring) |
| Sectors | 32 per Bank |
| Pages | 32 per Sector |
| Words | 8 per Page |
| Word length | 32 bits |
| Frequency | 16 MHz |
| Dynamic Consumption | 50 mA target average in HV Ops and READ |
| Static Consumption | 10 uA |
| Goal for retention time | 10 years |
