Standard Cell

* Standard cell devices do not have the concept of a basic cell and no components are prefabricated on the silicon chip.


*
The manufacturer creates custom masks for every stage of the device’s process which leads to a more efficient utilization of silicon as compared to gate arrays.

* Manufacturers supply hard-macro and soft-macro libraries containing elements of LSI and VLSI complexity, such as controllers, ALUs and microprocessors.


*
Additionally, soft-macro libraries contain RAM functions that cannot be implemented efficiently in gate array devices; ROM functions are more efficiently implemented in cell primitives.
