    摘要: Provided is a program method of a multi-bit memory device with memory cells arranged in rows and columns. The program method includes a programming each memory cell of the first group of memory cells to a state within a first group of states according to a verify voltage level of a first group of verify voltage levels within a first range of levels, and programming each memory cell of the second group of memory cells to a state within a second group of states according to a verify voltage level of a second group of verify voltage levels within a second range of levels. The lowest verify voltage level in the second range of levels is higher than the highest verify voltage level in the first range of levels. A first voltage difference between adjacent verify voltage levels within the first range of levels is different from a second voltage difference between the highest verify voltage level of the second group of verify voltage levels and the lowest verify voltage level of the third group of verify voltage levels.

    摘要: A data compression method includes receiving an input data stream including a previous data block and a current data block, and executing a first comparison of a part of the previous data block with part of a previous reference data block, and a second comparison of the current data block with a current reference data block, where the first and second comparisons are executed in parallel. The method further includes selectively, based on results of the first and second comparisons, outputting the current data block or compressing an extended data block, where the extended data block includes the part of the previous data block and the current data block.

    摘要: A memory system comprises a non-volatile memory device that stores user data and state information regarding the user data. In a read operation of the non-volatile memory device, a memory controller calculates a priori probabilities for the user data based on the state information, calculates a posteriori probabilities based on the a priori probabilities, and performs a soft-decision operation to determine values of the user data based on the a posteriori probabilities.
