MEMORY SYSTEM AND COMPUTER SYSTEM
First Claim
1. A memory system comprising:
- a plurality of first blocks provided for storing user information therein, to which first physical addresses which are not duplicate are assigned, respectively;
a plurality of second blocks provided for individually storing therein said first physical addresses of initial defective blocks out of said plurality of first blocks;
a plurality of third blocks provided for individually storing therein said first physical addresses of late defective blocks out of said plurality of first blocks; and
a computing device for obtaining said first physical address corresponding a logical address on the basis of said logical address, information stored in said second blocks, and information stored in said third blocks.

Abstract
A memory system of the present invention comprises a plurality of first blocks provided for storing user information therein, to which first physical addresses which are not duplicate are assigned, respectively, a plurality of second blocks provided for individually storing therein the first physical addresses of initial defective blocks out of the plurality of first blocks, and a plurality of third blocks provided for individually storing therein the first physical addresses of late defective blocks out of the plurality of first blocks. The memory system further comprises a computing device for obtaining the first physical address corresponding to a logical address on the basis of the logical address, information stored in the second blocks, and information stored in the third blocks.

20. A computer system comprising:
-
a computer for generating a logical address; a memory having a plurality of first blocks provided for storing user information therein, to which first physical addresses which are not duplicate are assigned, respectively; a controller memory having a plurality of second blocks provided for individually storing therein said first physical addresses of initial defective blocks out of said plurality of first blocks, to which second physical addresses which are not duplicate are assigned, respectively, and a plurality of third blocks provided for individually storing therein said first physical addresses of late defective blocks out of said plurality of first blocks, to which third physical addresses which are not duplicate are assigned, respectively; and a computing device for obtaining said first physical address corresponding to said logical address received from said computer on the basis of said logical address, information stored in said second blocks, and information stored in said third blocks.
