FLASH MEMORY DEVICE AND METHODS PROGRAMMING/READING FLASH MEMORY DEVICE

摘要

Multilevel flash memory and methods of programming/reading flash memory are disclosed. The multilevel flash memory device comprises a status detector configured to detect whether or not a target memory cell is programmed to an erase state, and a control logic unit controlling a program voltage applied to a neighboring memory cell adjacent to the target memory cell and to be programmed to one of a plurality of standard program states, such that the neighboring memory cell is programmed to a corresponding one of a plurality of correction program states different from the one of the plurality of standard program states.
