ABSTRACT:
A flash memory card is described which includes a first flash memory and a second flash memory. The first flash memory includes an unmasked first output that enters a first state if the first flash memory is ready and a second state if the first flash memory is busy. The second flash memory includes an unmasked second output that enters the first state if the second flash memory is ready and the second state if the second flash memory is busy. The flash memory card also includes a circuit for selectively providing one of (1) a masked first output (2) the unmasked first output, (3) a masked second output, and (4) the unmasked second output. A latch provides a first ready output signal for the flash memory card. The first ready output signal indicates a first transition from the second state to the first state by one of the unmasked first output of the first flash memory and the unmasked second output of the second flash memory. A circuit is also provided for clearing the first ready output signal from the latch.
