NON-VOLATILE MEMORY WITH DYNAMIC MULTI-MODE OPERATION

摘要

A method of programming a flash memory device which is dynamically configurable to store data in the single bit per cell (SBC) storage mode or the multiple bit per cell (MBC) mode, such that both SBC data and MBC data co-exist within the same memory array. The method including the step of determining a high reliability level or a low reliability level of the received data and programming data in the SBC mode if data is determined to be high reliability and in the MBC mode if data is determined to be low reliability.
