Common module for DDR SDRAM and SDRAM, has terminators connected to common module to output termination voltage and controller to transmit common/address and data signals to common module

摘要

The common module (12) includes a double data rate synchronous DRAM (DDR SDRAM) dual in-line memory module (DIMM) and a SDRAM DIMM. The terminators (60,62) are connected to the common module to output a termination voltage for common/address signals and data signals. A controller (10) transmits the common/address signals and data signals to the common module.
