Abstract: A computer implemented system and method is provided for generating a layout of the cell defining a circuit component, the layout providing a layout pattern for a target process technology. The method comprises obtaining an archetype layout providing a valid layout pattern for the cell having regard to design rules of the target process technology, and receiving an input data file providing a process technology independent schematic of the circuit component for which the cell is to be generated. A schematic sizing operation is then performed on the input data file, having regard to both schematic constraints applicable to the target process technology and layout constraints derived from the archetype layout, in order to generate an output data file providing a process technology dependent schematic of the circuit component. A cell generation operation is then performed using the output data file and layout data determined from the archetype layout in order to generate the layout of the cell.

Abstract: Within a memory 2 comprising an array 4 of bit cells 6 write driver circuitry 14 uses a boosted write signal which is boosted to a lower than normal level during a write operation. Column select transistors 16 are driven by column select circuitry 12. The column select signal is boosted to a lower than normal level when a column is unselected and to higher than a normal level when a column is selected. Voltage boost circuitry, such as charge pumps 20, 22 are employed within the column select circuitry 12 to achieve these boosted levels for the columns select signal.
