Abstract

The read margin and power consumption for various selector characteristics and bias schemes are analyzed during read operation. The 1/2 and 1/3 bias schemes exhibit different read operation properties. There is a trade-off between the read margin and power consumption that depends on the bias scheme and characteristics of the selector. The read margin of the 1/2 bias scheme is decreased at low on/off ratios because of the output voltage drop across the LRS cell. This drop is due to a rapid increase in the leakage current when a selector with low on/off ratio is used in the 1/2 bias scheme. Therefore, the bias scheme and selector should be selected appropriately according to the purpose of the application.
