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.

Semiconductor device, data programming device, and method for improving the recovery of bit lines of unselected memory cells for programming operation

FLASH memory device contains at least one memory stack. The stack of transistors includes a first (or source) selector transistor, a second (or drain) selector transistor, and a plurality memory cell transistors connected in series therebetween. During an erase operation, each of the first and second selector transistors has a bias applied that releases the select transistors from an electrically floating state together with biasing each of the memory cell transistors.

Systems and methods for erasing charge-trap flash memory

Disclosed herein is a device that includes a plurality of first word lines each extending from an associated one of the first terminals in a second direction toward to the second terminals and terminating between the first and second terminals, the second direction being substantially perpendicular to the first direction, and a plurality of second word lines each extending from an associated one of the second terminals in a third direction toward to the first terminals and terminating near to an end of an associated one of the first word lines, the third direction being opposite to the second direction, each of the second word lines being substantially aligned with an associated one of the first word lines.
