摘要： A system and method for a distributed metal routing is disclosed. An embodiment comprises a metal_0 layer with a metal_1 layer overlying the metal_0 layer. The metal_1 layer comprises separate parallel lines, with lines having different signals being distributed across the metal_1 layer. Such a layout decreases the parasitic resistance within the metal_0 layer as it decreases the distance current travels. Additionally, the distributed layout in metal_1 allows connections to be made to a metal_2 layer without the need for a hammer head connection of vias.

摘要： Some embodiments relate to a method of pre-coloring word lines and control lines within an SRAM integrated chip design to avoid timing delays that result from processing variations introduced through multiple patterning lithography processes. The method is performed by generating a graphical IC layout file having an SRAM circuit with a plurality of word lines and Y-control lines. The word lines and Y-control lines are assigned a color during decomposition. The word lines and Y-control lines are further pre-colored in a manner that deliberately assigns the pre-colored data to a same mask. Therefore, during mask building, data associated with pre-colored word and Y-control lines is sent to a same mask, regardless of the colors that are assigned to the data. By assigning word and Y-control lines to a same mask through pre-coloring, processing variations between the word and Y-control lines are minimized, thereby mitigating timing variations in an SRAM circuit.

摘要： In a digital memory with an array of bit cells coupled to word lines and bit lines, each bit cell having cross coupled inverters isolated from bit lines by passing gate transistors until addressed, some or all of the bit cells are switchable between a sleep mode and a standby mode in response to a control signal. A bit line bias circuit controls the voltage at which the bit lines are caused to float when in the sleep mode. A pull-up transistor for each bit line BL or BLB in a complementary pair has a conductive channel coupled to a positive supply voltage and a gate coupled to the other bit line in the pair, BLB or BL, respectively. A connecting transistor also can be coupled between the bit lines of the complementary pair, bringing the floating bit lines to the supply voltage less a difference voltage ΔV.

摘要： A memory device is provided with memory components and a clock skew generator, supporting at least two read and write operations that can occur coincidentally in read-read, read-write and write-write modes of operation of the memory device. The clock skew generator produces at least two stable and balanced clock channels carrying the at least two clock signals and varies relative timing of the clock signal edges so as to displace the edges in time, in those modes of operation wherein simultaneous edges would lead to detrimental loading.
