| Abstract: | Higher performance of SDRAM memory, more difficult to design the memory system. ODT technology is one key topic in memory system design. In this paper, some basic concepts about ODT such as structure of circuit, analysis for signal reflection and implementation of resister are introduced, and related implementation technology in memory system design are brought forward. Finally, signals analysis and compare between PCB termination and ODT termination are processed by simulation. |
