| 摘 要： | 针对低成本、低功耗无源射频电子标签,采用SMIC 0.18μm标准CMOS工艺设计实现了单栅、576bit的非挥发性存储器.存储器单元基于双向Fowler-Nordheim隧穿效应原理并采用普通的pMOS晶体管实现;编程/擦写时间为10ms/16bit.芯片实现块编程和擦写功能,通过提出一种新型的敏感放大器而实现了读功耗的优化.在电源电压为1.2V,数据率为640kHz时,读操作平均消耗电流约为0.8μA.

| Abstract: | Single-poly,576bit non-volatile memory is designed and implemented in an SMIC 0.18μm standard CMOS process for the purpose of reducing the cost and power of passive RFID tag chips. The memory bit cell is designed with conventional single-poly pMOS transistors, based on the bi-directional Fowler-Nordheim tunneling effect, and the typical program/erase time is 10ms for every 16bits. A new,single-ended sense amplifier is proposed to reduce the power dissipation in the current sensing scheme. The average current consumption of the whole memory chip is 0.8μA for the power supply voltage of 1.2V at a reading rate of 640kHz. |
