Abstract
A method and apparatus are disclosed for emulating a rotating disk drive using a removable ferroelectric solid state storage device having a multiplexed optical data interface in a microprocessor controlled storage system. The removable ferroelectric solid state storage device has non-volatile memory integrated circuit components in a ferroelectric random access memory (FRAM) pack. The ferroelectric memory pack utilizes the same read/write recording techniques as those for transferring data between a host computer and a rotating disk drive. The optical read and write data pass via a fiber optic read/write data multiplexor through a write data input buffer to a fiber optic light receiver, and a read data output buffer to a fiber optic light transmitter, and are thereby sent out on an ST506/SASI/ESDI/SCSI bus to a RAM memory pack controller.
