Abstract
Mis-programming of MSB data in flash memory is prevented by using ECC decoding logic on the flash die that error corrects the LSB values prior to the LSB values being used in conjunction with the MSB values to determine the proper reference voltage ranges. Error correcting the LSB page data prior to using it in combination with the MSB page data to determine the reference voltage ranges ensures that the reference voltage ranges will be properly determined and programmed into the flash cells.
