- Abstract
- A new low voltage operation of high voltage switching technique, which is capable of reducing leakage current by an order of three compared to conventional circuits, has been developed for sub-1.8 V low voltage mobile NAND flash memory. In addition, by using the proposed high voltage switch, chip size scaling can be realized due to reduced a minimum required space between the N-wells of selected and unselected blocks for isolation. The proposed scheme is essential to achieve low power operation NAND Flash memory, especially for mobile electronics.
