Question about FLASH programming

If I understand right, to program FLASH, I have first to erase all page. Even if I want to store only one word of data. Is that true?

But page erasing is very slow - about 20 ms regarding to datasheet. This is not acceptable for our application where a whole program loop take about 10 us and this FLASH programming (storing of one word) should occur quite often.

Is there any other way to store data in a non-volatile memory, which would be faster? Is it possible to store data without erasing a page each time?

Thanks
