Serial FRAM vs. EEPROM/Flash
Comparing with conventional non-volatile memory such as EEPROM and Flash, FRAM has advantages in faster writing, higher endurance and lower power consumption. Using FRAM instead of EEPROM and Flash has more advantages;
- Performance Improvement
FRAM enables to store data in writing even at sudden power outage because of fast writing speed. Not only that, FRAM can record data more frequent than EEPROM and Flash memories. When writing the data, EEPROM and Flash memories need high voltage and thus, consume more power than FRAM. Therefore, by using FRAM, a battery life in the battery-operated small device can be extended.
In summary, FRAM is;
- Enables to store data in writing at sudden power outage
- Enables to make fequent data logging
- Enables to extend battery life of battery-operated device
- Total Cost Reduction
In the case of parameter writing to each product at factory, FRAM can contribute to reduce manufacturing cost because FRAM can shorten the writing time compared with EEPROM and Flash memories. In addition, FRAM can give you one chip solution instead of multi-chip solution, e.g., 2 chips consisting of EEPROM+Flash, or 3 devices consisting of EEPROM+ SRAM+battery.
- Shorten the writing time when parameter writing at factory
- Reducing a number of parts used in end-product
Parallel FRAM vs. SRAM
FRAM with parallel interface, which has compatibility with battery backup SRAM, can become a substitution of the SRAM. By replacing SRAM with the FRAM, customers expect to get the following advantages.
- Total Cost Reduction
System using SRAM needs to keep battery-status check. By replacing with FRAM, customers can be freed from the burden of maintenance of battery check. In addition, FRAM does not require battery socket and backflow prevention diode and the space for them, which SRAM requires. FRAM's one chip solution can reduce the space and cost.
- Maintenance free; battery exchange is unnecessary
- Device downsizing; a number of parts for end-product can be reduced
- Eco-Friendly Product
Used battery becomes industrial waste. By replacing SRAM + battery with FRAM, unnecessary backup batteries can be reduced.
- Reduce battery disposal
