Abstract:
1. A method of reading data from a first group of memory locations in parallel, comprising: providing a list of defective locations among the first group of memory locations; storing data slated for the defective locations in a second group of redundant memory locations; providing a first group of data latches for latching data associated with the first group of memory locations and a second group of data latches for latching redundant data associated with the second group of redundant memory locations; sensing the data of the first and second group of memory locations; latching the sensed data into the first group and redundant data into the second group of data latches; transferring redundant data from the second group of data latches to data latches of corresponding to defective locations in the first group; and reading out the data from the data latches of the first group to a data bus regardless of any defective memory locations in the first group.
