An integrated circuit (IC) layout includes various memory blocks arranged in rows and columns, and a memory controller arranged in parallel to one of the rows and the columns. The IC layout further includes metal routes that are created over the memory blocks for coupling the memory and the memory controller and facilitating signal routing therebetween. Each memory block is coupled with the memory controller by way of one or more metal routes. When the memory controller is arranged in parallel to the rows, the one or more metal routes are created over memory blocks that are included in a column, whereas when the memory controller is arranged in parallel to the columns, the one or more metal routes are created over memory blocks that are included in a row.

Signal routing between memory and memory controller

An integrated circuit (IC) having a low leakage current mode of operation has a number of modules for running respective applications. The modules have respective cells and respective test scan chain elements. The IC also has a controller for configuring an active module to operate in a functional mode and a selected inactive module to operate in a low leakage current mode. Configuring the selected inactive module to operate in low leakage current mode includes enabling scan mode of the selected inactive module, and applying a low leakage vector of input signals from the controller to the cells of the inactive module using the scan chain. Functional data outputs of the inactive module are disabled during low leakage current mode. In the meantime, the active modules continue to operate in the functional mode.
