    Well, notice the overlapping between the terms EEPROM and Flash. EEPROM memories often have page-write capabilities, allowing them to write multiple bytes in a fixed time.

    So the criteria to look for is reasonably sized pages and reasonably fast page-write times. And to preferably look for SPI instead of I2C.

    An example is:
    www.st.com/.../456.jsp
    with 256 byte page write capability and < 1ms page write time.
