Abstract:
1. In a non-volatile memory partitioned into an user array portion and a redundant array portion such that a defective location in the user array portion is replaceable by a corresponding redundant location in the redundant array portion, a method of reading data from a group of memory locations straddling both the user and redundant array portions of the memory, comprising: providing a list of defective locations of the user array portion; providing a group of data latches for latching data associated with both the user and redundant array portions; sensing the group of memory locations to be read; latching the sensed data into the group of data latches; transferring redundant data from the data latches of the redundant array portion to the data latches of corresponding defective memory locations in the user array portion; and reading out the data from the data latches of the user array portion to a data bus regardless of any defective memory locations in the user array portion.
