ABSTRACT:
A solid state peripheral storage device receives an LSN address from a computer system and provides a mapping to a PSN data. The PSN data addresses memory units which are made out of solid state floating gate storage cells. In addition, a microsequencer controls the operation of the translation of the mapping of the LSN to PSN. Through the use of the mapping of LSN to PSN, defective sectors in the memory units can be mapped out and fresh, unused, defective-free sectors can then be replaced, all automatically, without user intervention. Finally, the microsequencer has error recovery routines to further enhance the reliability of the peripheral device.
