is it possible to write to flash

I see that there is a function to write SDRAM ( HAL_SDRAM_Write_32b ) but no FLASH.

I want to take data from ADC array[2000] and save so I do not loose when it is powered down.

And of course recall / display it later.

Flash memory very slow to erase/write. ADC stuff, would probably stream to an SD Card.

Ideally use an I2C or SPI EEPROM 8 pin device. they exist up to 32 kbyte. erase and write is fast with great rewrite cycle.
