Abstract

The keys to good signal integrity in a Graphic DDR3 (GDDR3) SDRAM interface for a bandwidth up to 1.4Gbps/pin are the minimization of input/output pin capacitance and the accurate control of the output data skew. The proposed pre-emphasis output buffer control scheme provides output data skew minimization without an increase of input/output pin capacitance. Compared to the conventional scheme, the output data aperture window of proposed scheme has increased by 18% and the data output skew has decreased by 48%.
