摘要： A method of reducing total power dissipation for logic cells includes selecting a distribution of logic cells corresponding to at least one path, computing a dynamic to static power ratio for each logic cell in the distribution of logic cells and ranking the dynamic to static power ratio for each logic cell into a lower group, a middle group and an upper group of logic cells. Additionally, the method includes swapping the lower group of logic cells and the upper group of logic cells for a reconfigured middle group of logic cells and verifying path timing for the reconfigured middle group of logic cells. Methods of reducing total power dissipation using Boolean equations and for logic cell sets are also provided.

摘要： A method and system for reconfiguring a memory array is disclosed. Initially, the cells in the memory array are patterned with substantially the same structure up to a predefined layer. Thereafter, the memory array is reconfigured by patterning the cells above the predefined layer such that a first plurality of cells function as memory cells, and a second plurality of cells are patterned as a dummy row or column that function as a breakpoint for the memory array.

摘要： Fuses, and optionally metal pads, are formed over a layer of low k dielectric material structure having first openings lined with conductive barrier material and filled to form metal interconnects in the upper surface of the low k dielectric material. A dielectric layer is formed over the low k dielectric material and over the metal interconnects, and patterned to form second openings therein communicating with the metal interconnects. A conductive barrier layer is formed over this dielectric layer in contact with the metal interconnects, and patterned to form fuse portions between some of the metal interconnects, and a liner over one or more of the metal interconnects. A dielectric layer is then formed over the patterned conductive barrier layer to form a window above each fuse, and patterned to form openings over at least some of the conductive barrier liners filled with metal to form metal pads.

摘要： Described embodiments provide for a memory system which power-gates a memory operating at a first clock. Control logic in the memory system activates, during a rising edge of a second clock, the memory from a sleep mode. The memory is accessed. After a cycle of the first clock, the control logic asserts a power-gating signal, thereby returning the memory to the sleep mode. The frequency of the second clock is less than a frequency of the first clock.
