ABSTRACT:
An apparatus for emulating a floppy disk drive using flash EPROMs. The apparatus transfers data between a floppy disk controller and a flash EPROM memory module, wherein the floppy disk controller operates under a first protocol and transmits requests to write data to a floppy disk in response to address marks. The flash EPROM operates under a second protocol. The invention includes control means compensating for the difference in the two protocols. In addition, the control means provides for the situation when power is terminated during the write process. Furthermore, the invention includes a means for organizing and reorganizing data in the flash EPROM to make most effective and efficient use of the flash EPROM memory module.
