Abstract
A semiconductor device capable of performing high-speed read or high-reliability read is provided. A reading method of a NAND flash memory includes: pre-charging a sensing node through a voltage-supply node; discharging the sensing node to the voltage-supply node for a prescribed operation; recharging the sensing node by the voltage-supply node after the prescribed operation; and discharging a NAND string and sensing a memory cell.
