ABSTRACT:
A system and method for providing a flash memory is disclosed. The flash memory includes a plurality of memory cells. Each memory cell includes a source and a gate. The method and system include providing a plurality of word lines and a plurality of select devices. Each word line is coupled with the gate of each memory cell of a portion of the plurality of memory cells. Each word line provides a specific voltage to the portion of the plurality of memory cells during a read of a memory cell of the portion of the plurality of memory cells. The plurality of select devices correspond with the plurality of word lines. Each select device is coupled with the source of each memory cell of the portion of the plurality of memory cells coupled with the corresponding word line. Each select device couples the source of each memory cell of the portion of the plurality of memory cell with a specific potential during the read of the memory cell. The method and system reduce the number of memory cells coupled in parallel with the memory cell during the read.
