SEMICONDUCTOR MEMORY DEVICE

摘要

A NAND DC-DC converter includes two output terminals. Each output terminal is connected to several multi-chip packages in each of which a plurality of NAND flash memory chips are provided. Phases of voltages which are output from the output terminals are different by 180 degrees. In addition, a maximum of the output voltages are approximately one-half of a maximum of an input voltage supplied to the NAND DC-DC converter
