1. A method comprising: receiving a write-data in a GIOC; selecting at most one global sub-write circuitry of the GIOC from a plurality of global sub-write circuitries based on the received write-data; transmitting a global write clock signal to the selected global sub-write circuitry; storing the write-data through the global write clock signal into the selected global sub-write circuitry of the GIOC; and decoupling the selected global sub-write circuitry from the global write clock signal based on the storing.
