With lead-free initiatives being implemented globally, nvSRAMs have become a popular choice for NVRAM selection. The nvSRAM is a single monolithic solution when compared to a multiple component solution. nvSRAM can easily replace the BBSRAM with the following benefits:
-
Lower Cost
-
Higher reliability
-
Smaller board space and lower height
-
Improved manufacturing
-
RoHS compliance
-
Higher Performance
This application note outlines the BBSRAM and nvSRAM memory architecture and comparison of their features. More...
