Zusammenfassung:Various implementations described herein are related to a device having a storage node with a bitcell. 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.
