Flash memory apparatus

Abstract

A flash memory apparatus includes a plurality of memory sectors and a plurality of path transistors, and each memory sector has a local low voltage line, and each path transistor corresponds to one of the memory sectors, and the path transistors are installed in an alignment direction of the memory sectors. One of the path transistors is installed between two adjacent memory sectors, whose gate is connected to a sector select signal line, and whose drain is connected to the local low voltage line of the corresponding memory sector, and whose source is connected to a global low voltage line, and the global low voltage line is installed at an angle substantially equal to 90 degrees across the gate, so as to save the area occupied by peripheral circuits in the path transistors, and lower the manufacturing cost of the flash memory apparatus.
