摘　　要：在语音合成集成电路(IC)中,需要存储大量的程序和语音数据,因此内存储器的集成度、读取速度及可靠性成为影响一款芯片生产成本和性能参数的关键指标。存储器有很多分类,掩模只读存储器(ROM)以其较高的集成度和较低的成本在中低档消费类语音合成IC中有着较为广泛的应用。给出一种语音合成IC中掩模ROM的解决方案,分别介绍3个组成部分:存储单元阵列、地址译码器和读出放大器的设计实现。采用该方案可以有效提高掩模ROM的集成度、读取速度及可靠性,有效降低语音合成IC的生产成本、提高其性能和市场竞争力。Much procedure and voice data are needed to store in voice synthesizer IC, so the integration, read speed and reliability of internal memory become the key index which will affect the manufacture cost and performance parameter of a chip. In the classification of the memory,mask ROM is widely used in middle or low price consumed voice synthesizer IC for its upper integration and lower cost. In this artiele,a solution to mask ROM will be given out in Voice Synthesizer IC,and the realization of the three parts about memory array, address decoder and sense amplifier will be introduced. The integration, read speed and reliability of the mask ROM will be improved, the manufacture cost of the voice synthesizer IC will be reduced, the performance be heightened,and the market competition capacity be advanced availably if this project being used.
