嵌入式静态随机存储器的低功耗设计

介绍了多种最新的嵌入式静态随机存储器低功耗设计技术。存储器的总功耗为动态功耗和静态功耗之和。动态功耗又分读周期功耗和写周期功耗。减少动态功耗的主要技术：（1）降低开关电容。（2）降低充放电电压摆幅等。减少静态功耗的主要技术是降低衬底电流和栅电流等。对多种低功耗技术做了分析和总结，并提出了改进意见。

Low Power Design of eSRAM

Several latest techniques in low-power design of eSRAM are presentet.The total power of eSRAM is consisting of active power dissipation and static power dissipation.Active power dissipation is consisting of power during read cycle and write cycle.The main techniques used to decrease active power are :(1)reduce switch capacitance.(2)Minimize level of voltage which to precharge or discharge capacitance.The main techniques used to decrease static power are:reduce current from substrate and mosfet gate.Analysis and summary about several low power design techniques,and make some suggestions to improve.
