A New Low Power 9T SRAM Cell based on CNTFET at 32nm Technology Node
نویسنده
چکیده
Abstarct---This paper proposes a new design of highly stable and low power SRAM cell using carbon nanotube FETs (CNTFETs) at 32nm technology node. As device physical gate length is reduced to below 65 nm, device non-idealities such as large parameter variations and exponential increase in leakage current make the I-V characteristics substantially different from traditional MOSFETs and become a serious obstacle to scale devices. CNFETs have received widespread attention as one of the promising successor to MOSFETs. The proposed circuit was simulated in HSPICE using 32nm Stanford CNFET model. Analysis of the results shows that the proposed CNTFET based 9T SRAM cell, power dissipation, and stability substantially improved compared with the conventional CMOS 6T SRAM cell by 51% and 58% respectively at the expense of 4% write delay increase.
