“…However, NEMs have relatively long mechanical switching delay [6] compared to the intrinsic delay of CMOS devices, and to this date, they suffer from low endurance [15]. To get the best of both worlds, researchers have combined NEMs and CMOS to build low-power and high performance circuits for critical components [9], [10].…”

Abstract-In this paper we propose a novel Content Addressable Memory (CAM) cell, NEMsCAM, based on both Nanoelectro-mechanical (NEM) switches and CMOS technologies. The memory component of the proposed CAM cell is designed with two complementary non-volatile NEM switches and located on top of the CMOS-based comparison component. As a use case for the NEMsCAM cell, we design first-level data and instruction Translation Lookaside Buffers (TLBs) with 16nm CMOS technology at 2GHz. The simulations show that the NEMsCAM TLB reduces the energy consumption per search operation (by 27%), write operation (by 41.9%) and standby mode (by 53.9%), and the area (by 40.5%) compared to a CMOSonly TLB with minimal performance overhead.

“…NEM relays are composed of 4 terminals like MOSFET devices. However, in NEM relays, the mechanical channel is actuated by electrostatic force, instead of the electrical channel [2][3][4][5][6]. When the channel is turned off in NEM relays, it is disconnected mechanically from the both source and drain.…”

“…Even a small amount of variations in mechanical channel's dimensions can result in significantly large distribution of electrical parameters of NEM relays [2,10]. For example, a 10% variation in the air gap of mechanical channel can make the largest pull-in voltage 3.6 times larger than the smallest pull-in voltage.…”

Abstract-For some low-frequency applications such as power-related circuits, NEM relays have been known to show better performance than MOSFETs. For example, in a step-down charge pump circuit, the NEM relays showed much smaller layout area and better energy efficiency than MOSFETs. However, severe process variations of NEM relays hinder them from being widely used in various low-frequency applications. To mitigate the process-variation problems of NEM relays, in this paper, a new NEMrelay charge pump circuit with the self-adjustment is proposed. By self-adjusting a pulse amplitude voltage according to process variations, the power consumption can be saved by 4.6%, compared to the conventional scheme without the self-adjustment. This power saving can also be helpful in improving the power efficiency of the proposed scheme. From the circuit simulation of NEM-relay charge pump circuit, the efficiency of the proposed scheme is improved better by 4.1% than the conventional.
