摘要： The storage device includes a storage unit configured to store data, an error controlling unit configured to correct an error of the data read out from the storage unit according to at least one read level, and a read level controlling unit configured to control the at least one read level when the error is uncorrectable. The read level controlling unit is configured to measure a distribution of memory cells of the storage unit, configured to filter the measured distribution, and configured to reset the at least one read level based on the filtered distribution.

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.
