Patent Images
1. An apparatus configured to generate error detection codes, comprising:
- an error detection code generation unit configured to generate virtual error detection codes using virtual data bus inversion (DBI) information and data; and
an error detection code regeneration unit coupled to the error detection code generation unit, the error detection code regeneration unit configured to generate error detection codes using even and odd number information, which define whether the number of data associated with generation of the error detection codes is even or odd, DBI information associated with the even and odd number information, and the virtual error detection codes.

Abstract
An apparatus for generating error detection codes can include an error detection code generation unit configured to generate virtual error detection codes using virtual DBI information and data, and an error detection code regeneration unit configured to generate error detection codes using even and odd number information which define whether the number of data associated with the generation of the error detection codes is even or odd, DBI information associated with the even and odd number information, and the virtual error detection codes.

8. An apparatus for generating error detection codes, comprising:
-
a data bus inversion unit configured to generate DBI information using data; an error detection code generation unit coupled to the data bus inversion unit configured to generate virtual error detection codes before the DBI information is completely generated, using virtual DBI information, and the data; and an error detection code regeneration unit coupled to the error detection code regeneration unit, the error detection code regeneration unit configured to generate error detection codes using even and odd number information, which define whether the number of data which are associated with generation of the error detection codes is even or odd, DBI information associated with the even and odd number information, and the virtual error detection codes. - View Dependent Claims (9, 10, 11, 12, 13, 14)
