ABSTRACT:
A non-volatile memory system comprises a non-volatile memory and a memory controller controlling the non-volatile memory. The non-volatile memory has a pseudo pass function of returning a pass as a status even if a bit error reaching allowable number of bits occurs after at least one of a write or erase sequence is completed. The memory controller has an allowable bit change function of changing the upper limit value of the allowable number of bits.
