    • An apparatus and method for combating the effects of bias temperature instability (BTI) in a memory cell. Bit lines connecting to a memory cell contain two alternate paths criss-crossing to connect a lower portion of a first bit line to an upper portion of a second bit line, and to connect a lower portion of the second bit line to an upper portion of the first bit line. Alternative to activating transistors on the bit lines to read and write to the memory cell, transistors on the alternative paths may be activated to read and write to the memory cell from the opposite bit lines. The memory cell may be read through the bit lines to a sense amplifier, the transistors on the bit lines are subsequently deactivated and the transistors on the alternate paths are activated to write transposed bit values to the memory cell, thereby reversing the biases.

A group of IC components that are functionally distinct or have mutually exclusive and/or quasi-mutually exclusive, (ME/QME) operating patterns (i.e. alternate or partially overlapping duty cycles) can be powered with a single power cell. An integrated circuit design tool can identified components in an integrated circuit design that have the ME/QME operating patterns. These cells can be collocated in close proximity to each other and power management system components can be placed in this area such that a multiple signal processing cells can share a single power line and a single power cell. Such a configuration can greatly reduce the size of a power management system for an integrated circuit.
