摘要:
A method of programming a flash memory device comprises programming selected memory cells, performing a verification operation to determine whether the selected memory cells have reached a target program state, and determining a start point of the verification operation based on a programming characteristic associated with a detection of a pass bit during programming of an initial program state.
摘要:
A memory system comprises a multi-bit memory device and a memory controller that controls the multi-bit memory device. The memory system determines whether a requested program operation is a random program operation or a sequential program operation. Where the requested program operation is a random program operation, the memory controller controls the multi-bit memory device to perform operations according to a fine program close policy or a fine program open policy.
摘要:
An apparatus and a method for reading from a non-volatile memory whereby soft decision data is used to determine the reliability of hard decision data. The hard decision data read from the non-volatile memory is de-randomized and the soft decision data read from the non-volatile memory is not de-randomized. Using the soft decision data, the hard decision data is decoded.
