摘要
This paper presents an analytic model for NAND flash array where channel coupling embodies. Channel coupling effect which is becoming a more serious issue in developing high-density flash memory devices should be effectively suppressed. By applying the coupling model to a 30-nm NAND flash product, the simulation showed a good agreement with the measurement results. Also, complex problems in scaled NAND flash memories could be accurately explained by circuit simulations. This evaluation will be useful in developing high-density multi-level cell (MLC) NAND flash technologies. (C) 2011 The Japan Society of Applied Physics
