SEMICONDUCTOR MEMORY DEVICE AND DATA PROCESSING METHOD THEREOF

摘要

PURPOSE: A semiconductor memory device and a data processing method thereof are provided to improve the reliability of data by programming the state of memory cells to avoid an arrangement which causes an error. CONSTITUTION: Data to be programmed in the row and column of a nonvolatile memory is arranged according to row and column directions. The data is coded to a modulation code according to the row or column directions. A modulation coding unit(110) codes program data from a host with a modulation coding method and transmits the coded program to a nonvolatile memory device(120). The modulation coding unit decodes the read data outputted from the nonvolatile memory device and transmits the decoded data to the host. The nonvolatile memory device writes the program data supplied from the modulation coding unit on the nonvolatile memory cells of a cell array(121). The coded program data is simultaneously loaded on a page buffer(122) of the nonvolatile memory device.
