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. Such an approach enables both the schematic and layout to be co-optimised during generation of the layout of the cell.

Abstract: A memory device and a method of operating the memory device are provided. The memory device comprises a plurality of storage units and access control circuitry. The access control is configured to receive an access request and in response to the access request to initiate an access procedure in each of the plurality of storage units. The access control circuitry is configured to receive an access kill signal after the access procedure has been initiated and, in response to the access kill signal, to initiate an access suppression to suppress the access procedure in at least one of the plurality of storage units. Hence, by initiating the access procedures in all storage units in response to the access request, e.g. without waiting for a further indication of a specific storage unit in which to carry out the access procedure, the overall access time for the memory device kept low, but by enabling at least one of the access procedures later to be suppressed in response to the access kill signal dynamic power consumption of the memory device can be reduced.

Abstract: A memory has a normal mode and a power saving mode. The memory has bitline precharge circuitry which during the normal mode selectively couples a pair of bitlines to a precharge node to charge the bitlines to a given voltage level. During the power saving mode the bitlines are isolated from the precharge node. Voltage control circuitry is provided to maintain the precharge node at a first voltage level during the normal mode and at a second voltage level less than the first voltage level during the power saving mode. By reducing the voltage level at the precharge node during the power saving mode, the amount of inrush current occurring when switching from power saving mode to normal mode can be reduced, and this enables the wakeup time to be reduced when returning from power saving mode to normal mode.

The device may have a first stage that performs a first write based on an internal bitline signal, a first write wordline signal and a second write wordline signal. The first stage outputs the internal bitline signal. The device may have a second stage that receives the internal bitline signal and performs a second write of the internal bitline signal to the bitcell. The device may have a third stage with write wordline ports and write bitline ports. The third stage provides the internal bitline signal based on a selected write wordline signal from a write wordline port of the write wordline ports and based on a selected bitline signal based on a write bitline port of the write bitline ports.
