摘要：

提出了一种利用同步双端口存储器IP和标准单元来实现嵌入式可编程存储器中的字宽配置的方案以降低设计的复杂性,提高设计效率. 通过寄存输出控制信号来优化嵌入式可编程存储器混合宽度配置的实现结构以增强读出数据的稳定性. 对比试验表明,优化后的结构还有利于提高复杂实现电路的性能. 该优化结构的嵌入式可编程存储器已在SMIC 0.18μm 1P6M CMOS工艺线上流片. 测试结果表明,其读出数据具有良好的稳定性,在读出时间方面与相近工艺、相同存储容量的采用全定制方法设计的商用嵌入式可编程存储器相当.

Abstract:

A scheme for realization of word-width configuration in embedded programmable memories using synchronous dual-port memory IP and standard cell is proposed. The method reduces the implementing complexity and further improves the designs efficiency. The structure of embedded programmable memorys word width configuration is optimized by registering the output control signals to improve the readout datas stability. Experiment results show that the optimized structure has the advantage of implementing complex circuits with higher performance. The embedded programmable memory based on this optimized structure has been fabricated in SMIC 0.18μm 1P6M CMOS process. According to the measurement results, the fabricated embedded programmable memorys readout data has good stability and it has comparable performance in readout time with the reference to those full custom commercial embedded programmable memories based on the similar process and memory capacity.

Key words: embedded programmable memory, word width configuration, memory IP, standard cell
