ABSTRACT:
A verify unit incorporated in an electrically erasable and programmable read only memory device concurrently verifies erased state for selected floating gate type memory transistors in an erase-and-verify mode, and generates a detecting signal representative of an entry of the selected floating gate type memory transistors into the erased state so as to cause a sense amplifier unit to supply a verify signal to an external eraser.
