wherein the column select section includes at least one swizzle layer and at least one column select line, the at least one column select line configured to receive the at least one column select signal, and

wherein the at least one swizzle layer is disposed so as to connect the at least one column select line to the second bit-lines of the at least one second memory sub-array, and the at least one swizzle layer is configured to route the at least one column select signal to the second bit-lines of the at least one second memory sub-array.

2. The apparatus of claim 1 , wherein at least four bit-lines are disposed between each selected bit-line of the at least one first memory sub-array and each selected bit-line of the at least one second memory sub-array.

3. The apparatus of claim 1 , wherein the column select section further includes at least one second column select line that is configured to receive the at least one column select signal and configured to route the at least one column select signal to the first bit-lines of the at least one first memory sub-array.

4. The apparatus of claim 1 , wherein the at least one swizzle layer is disposed in at least one gap portion of the memory array.

5. The apparatus of claim 1 , wherein the plurality of memory sub-arrays further includes at least one third memory sub-array and at least one fourth memory sub-array,

wherein the column select section includes at least one second swizzle layer and at least one second column select line, the at least one second column select line configured to receive at least one second column select signal, and

wherein the at least one second swizzle layer is disposed so as to connect the at least one second column select line to the first bit-lines of the at least one third memory sub-array, and the at least one second swizzle layer is configured to route the at least one second column select signal to the first bit-lines of the at least one third memory sub-array.

6. The apparatus of claim 5 , wherein the column select section further includes at least one third column select line that is configured to receive the at least one second column select signal and configured to route the at least one second column select signal to the second bit-lines of the at least one fourth memory sub-array.

7. The apparatus of claim 5 , wherein the first and second swizzle layers are disposed in at least one gap portion of the memory array.

8. The apparatus of claim 1 , wherein the memory operations include at least one of read operations, write operations, or ECC prefetch operations.

9. A method, comprising:

providing at least one column select signal for selecting corresponding bit-lines in a memory array for memory operations;

routing the at least one column select signal such that non-adjacent bit-lines are exclusively selected for the memory operations;

segmenting the memory array into a plurality of memory sub-arrays, the plurality of memory sub-arrays including at least one first memory sub-array and at least one second memory sub-array;

disposing first bit-lines and second bit-lines in an alternating column format in each memory sub-array;

routing at least one column select signal to the first bit-lines in the at least one first memory sub-array;

routing the at least one column select signal to the second bit-lines in the at least one second memory sub-array;

disposing at least one swizzle layer and at least one column select line in the memory array such that the at least one swizzle layer connects the at least one column select line to the second bit-lines of the at least one second memory sub-array, the at least one column select line configured to receive the at least one column select signal; and

routing the at least one column select signal to the second bit-lines of the at least one second memory sub-array via the at least one swizzle layer.

10. The method of claim 9 , further comprising disposing at least four bit-lines between each selected bit-line of the at least one first memory sub-array and each selected bit-line in the at least one second memory sub-array.

11. The method of claim 9 , further comprising:

receiving the at least one column select signal via at least one second column select line; and

routing the at least one column select signal to the first bit-lines of the at least one first memory sub-array via the at least one second column select line.

12. The method of claim 9 , wherein the at least one swizzle layer is disposed in at least one gap portion of the memory array.

13. The method of claim 9 , wherein the plurality of memory sub-arrays further includes at least one third memory sub-array and at least one fourth memory sub-array, the method further comprising:

disposing at least one second swizzle layer in the memory array such that the at least one second swizzle layer connects at least one second column select line to the first bit-lines of the at least one third memory sub-array;

receiving at least one second column select signal via the at least one second column select line; and

routing the at least one second column select signal to the first bit-lines of the at least one third memory sub-array via the at least one second swizzle layer.

14. The method of claim 13 , further comprising:

receiving the at least one second column select signal via at least one third column select line; and

routing the at least one second column select signal to the second bit-lines of the at least one fourth memory sub-array via the at least one third column select line.
