ABSTRACT:
Solid-state flash electrically erasable and programmable read-only-memory ("flash EEPROM") system is combined with a rotating disk drive memory to provide mass program and data storage in a computer system. A common memory controller directs system generated memory addresses in a disk format to either the EEPROM system or disk memory. The blocks of data handled by the EEPROM system have the same size and other attributes as sectors of data handled by the disk system, thereby making it transparent to the computer system processor as to whether it is accessing the EEPROM or disk portion of the storage system. A particular program or data file may then be stored in the portion of the memory system best suited to handle it, and thus take advantage of the different features and characteristics of EEPROM and magnetic media disk memory.
