Abstract

Disclosed is an architecture for an output driver that does not employ level shifters in the high speed data path. Since the proposed architecture is free from level shifters in the high speed data path, it provides better performance across PVT corners. The disclosed output driver usages a hybrid pullup driver which makes it compatible for the wide range of DRAM supply range. This approach allows for significant savings for electronic design area and dynamic power.
