Memory with interleaved read and redundant columns

An apparatus comprising:

• a memory block having a plurality of columns, each of the columns comprising a bit line and a plurality of memory cells electrically coupled to the bit line, the plurality of columns comprising:
• a plurality of regular interleave groups of regular columns;
• and
• a plurality of redundant interleave groups of redundant columns, wherein each of the plurality of redundant interleave groups is associated with a corresponding regular group of the plurality of regular interleave groups;
• wherein the apparatus is configured to store data associated with a defective regular column of a first regular interleave group of the plurality of regular interleave groups in a redundant column of a redundant interleave group corresponding to a different regular interleave group of the plurality of redundant interleave groups, and
• wherein the apparatus is configured to perform an interleave read scheme from the memory block.

An apparatus comprising:

• a memory block having a plurality of columns, each of the columns comprising a bit line and a plurality of memory cells electrically coupled to the bit line, the plurality of columns comprising a first regular interleave group of regular columns, a second regular interleave group of regular columns, a first redundant interleave group of redundant columns associated with the first regular interleave group, and a second redundant interleave group of redundant columns associated with the second regular interleave group;
• and
• a multiplexer configured to:
• receive data corresponding to the first regular interleave group, the second regular interleave group, the first redundant interleave group, and the second redundant interleave group;
• and
• sequentially output data associated with addresses of regular columns of the first regular interleave group and data associated with addresses of regular columns of the second interleave group in an alternating manner to perform an interleaved read scheme,
• wherein the multiplexer is configured to output data stored at an address of a redundant column in the first redundant interleave group in place of data at an address of a defective regular column in the first regular interleave group, and
• wherein the multiplexer is configured to output data stored at an address of a redundant column in the second redundant interleave group in place of the data at an address of the different defective regular column in the first regular interleave group.
