In one embodiment, a memory block includes one or more bit lines that each include two or more cells. Each cell in each bit line has a distance from a sense amplifier coupled to the bit line, and each of one or more of the cells in each of one or more of the bit lines has a delay particularly set according to the distance of the cell from the sense amplifier coupled to the bit line.

Setting threshold voltages of cells in a memory block to reduce leakage in the memory block

A method of forming a memory cell includes coupling a first transistor between a supply rail of a memory cell and a node operable to accept a supply voltage. The method further includes coupling a second transistor between a ground rail of the cell and a node operable to accept a ground. In one embodiment, the method includes forming the cell to accept selectively applied external voltages, wherein the external voltages are selected to minimize leakage current in the cell. In another embodiment, the method includes forming at least one of the first and the second transistors to have a channel width and/or a threshold voltage selected to minimize a total leakage current in the cell.
