Abstract
An address sequencer is fabricated on a semiconductor substrate having flash memory cells fabricated thereon for sequencing through the flash memory cells during BIST (built-in-self-test) of the flash memory cells. The address sequencer includes an address sequencer control logic and address sequencer buffers fabricated on the semiconductor substrate. The address sequencer buffers generate a plurality of bits indicating an address of the flash memory cells. The address sequencer control logic controls the buffers to sequence through a respective sequence of bit patterns for each of a plurality of BIST modes.
