Abstract
A memory system includes a host, a flash memory that is configured to store multi-bit data in one memory cell, and a memory controller that is configured to control programming of multi-bit data provided by the host into the flash memory. When an nbit is normally programmed, and a fail occurs in programming an n+1th bit in the flash memory, a memory block of the flash memory including a fail cell is operated in an operation mode of the nth or lesser bit. Related memory systems and methods are also provided.
