<p><P>PROBLEM TO BE SOLVED: To provide a semiconductor storage device capable of allocating data for scrambling by chip without the need to manage and write seed data for scrambling. <P>SOLUTION: If an authentication key input by a user into an authentication key register 22 matches a determination key preset in a determination key register 23, read data RD read out from a memory chip 10 is output as it is as data DT via a selector 25. If they do not match, the read data RD (scrambled data SRD) scrambled with seed data SD that is location information about defective memory cells output from a fuse circuit 12 is selected by the selector 25 to be output as data DT. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
