SEMICONDUCTOR DEVICE, DATA PROGRAMMING DEVICE, AND METHOD FOR IMPROVING THE RECOVERY OF BIT LINES OF UNSELECTED MEMORY CELLS FOR PROGRAMMING OPERATION

摘要

A device comprises a non-volatile memory array, a first selection circuit selecting whether to make a first connection path between a first bit line and a first circuit node, and selecting whether to make a second connection path between the first bit line and a second circuit node, a power supplying circuit supplying a power supply voltage to the first circuit node, the power supply voltage being, when the first connection path is selected to be made, supplied to the first bit line, and a first voltage supplying circuit supplying a first voltage to the second circuit node, the first voltage being, when the second connection path is selected to be made, supplied to the first bit line, the first voltage and the power supply voltage being higher than a ground potential, and the first voltage being higher than the power supply voltage.
