Semiconductor storage system.

摘要

A semiconductor storage system comprises a semiconductor storage element array (1) including a plurality of semiconductor memory elements, a data bus (2) for transferring data to said semiconductor storage element array, an address bus (4) for inputting an address to said semiconductor storage element array, a read/write controller (5) for controlling read/write of the data written to said semiconductor storage element array, an interface control module (6) for controlling a transfer/receipt of data and commands to and from an outside system, a microprocessor (8) for generalization-controlling said read/write controller and said interface control module, a defect address memory (9) for storing and outputting information on an address where at least one defective bit exists and an alternate address to be alternated with said address, and a defect address manipulating circuit (12) for alternating said alternate address with said address where said defective bit exists in accordance with an output of said defect address memory. <IMAGE>
