Claim 11:
12. The memory device of claim 11, wherein:
the well strap cells are N-type well strap cells or P-type well strap cells,
an N-type well strap cell includes a layout different from that of any bit cell and that of any abutting dummy cell and includes an N+ semiconductor material in an N-type well, the N+ semiconductor material being electrically connected to a first power line, and
a P-type well strap cell includes a layout different from that of any bit cell and that of any abutting dummy cell and includes a P+ semiconductor material in a region outside the N-type well, the P+ semiconductor material being electrically connected to a second power line electrically isolated from the first power line.
