In this paper we propose a new Built in Current Sensor (BICS) to detect single event upsets in SRAM. The BICS is designed and validated for 100nm process technology. The BICS reliability analysis for process, voltage, temperature, and power supply noise are provided. This BICS detect various shapes of current pulses generated due to particle strike. The(More)
In this paper, we introduce an approach for computing soft error susceptibility of nodes in large CMOS circuits at the transistor level. The node sensitivity depends on the electrical, logic, and timing masking. An efficient technique is developed to compute the electrical masking of nodes from the characterization tables and the inverse pulse propagation.(More)
Soft errors in semiconductor memories occur due to charged particle strikes at the cell nodes. In this paper, we present a new asymmetric memory cell to increase the soft error tolerance of SRAM. At the same time, this cell can be used at the reduced supply voltage to decrease the leakage power without significantly increasing the soft error rate of SRAM. A(More)
— In this paper, we present an analysis methodology to compute circuit node sensitivity due to charged particle induced delay (timing) errors, Soft Delay Errors (SDE). We define node sensitivity metric and describe a step by step procedure to compute node sensitivity. We use mixed-mode simulations to extract accurate current pulses for the characterization(More)
