Abstract
Semiconductor memory device and method of operating same includes reading data stored in memory cells of a page; performing an error correction loop (ECC loop) including performing an error checking and correcting operation (ECC) on the read data; determining a number of bit errors in the read data; and when the number of bit errors is greater than a maximum number of correctable bits, incrementing the number of ECC iterations (ECC count) and increasing the maximum number of correctable bits; storing the ECC count until the number of bit errors is less than the maximum number of correctable bits; and programming corrected data to the memory cells when the stored ECC count is more than preset number.
