Abstract
A data transmission system using a pair of complement signals (STROB/STROB#) as an edge-aligned strobe signal and input/output buffers therein. Several data signals and a pair of STROB/STROB# signals are transmitted from a data output device to a data input device therein. These data signals and the STROB/STROB# signals are edge-aligned and transmitted through the same transmission architecture. The data input device includes several data comparators for generating output signals from the received data signals using the received STROB/STROB# signals as a dynamic reference voltage. In addition, the data input device further includes several comparators and delay elements for generating a pair of non-inverting/inverting latch clock signals from the STROB/STROB# signals. Each of the output signals is sent to two data latch circuits for outputting two latched data based on the latch clock signals.
