| Double Cell Serial EEPROM Memories for double data protection |
| ROHM offers an extra safe Serial EEPROM memories with Double Cell technology for protecting from data loses during operation. Double Cell technology reduces dramatically product failure ratio even in harsh environment and unstable power source applications. With doubling every cell from EEPROM memory array, ROHM ensures that if a bit error occurs in one cell, the data will be retained in the secondary cell. Extra protection is added by Double Reset functionality which protects from data loses during power up and down. All this ends with highly reliable EEPROM memory. |
| Three types of serial EEPROMs are availbale from ROHM, with standard MICROWIRE, SPI or I2C serial bus. |
