摘　　要：文章详细描述了一种集成在OLED显示控制驱动芯片中的双端口SRAM的设计,从电路和版图两方面对SRAM的核心部分进行了详细描述,并且设计了一种可用于OLED显示控制驱动芯片中的96×64×16位的双端口SRAM,最后给出了测试结果,验证了设计的正确性。This paper concentrates on providing a practical example addressing difficulty in circuit and layout design of dual-port SRAM （DPSRAM） which is embedded in display control/driver circuit. The initial part of this article explores the special requirements and characteristics of embedded DPSRAM used in the display control/driver circuits. A detailed design of DPSRAM is provided in the next part, including the memory cell, decoders and Sense Amplifier （SA）. Next presents a brief summary of the AC electrical characteristics of this embedded DPSRAM with the layout of the whole chip attached. Last gives the test report of the SRAM to verify the correctness of DPSRAM.
