FLASH MEMORY DEVICE AND SYSTEMS AND READING METHODS THEREOF

摘要

PURPOSE: A flash memory device, a system and a reading method thereof are provided to improve reliability for the reading result of the flash memory by effectively compensating the influence of a coupling generated between adjacent memory cells. CONSTITUTION: A data is read from adjacent memory cells connected to the adjacent word line of selected memory cells(S1000). A coupling compensation parameter is determined based on the data status of the determined adjacent memory cells(S1100). A data is read by applying the determined coupling compensation parameter to each memory cell connected to a selected word line(S1200). The data read from the selected memory cells is selectively latched at each bit line according to the program state of adjacent memory cells(S1300).
