Problem 1: Consider a DRAM cell storing logic ' 1 '. The storage capacitance of the DRAM cell is CS = 50 fF and the bitline capacitance is CBL = 450 fF. The supply voltage (VDD) is 1 V and the threshold voltage of the access device is VT = 0.5 V. The constant leakage current for the cell is 250 pA at room temperature (T = 300 K). (a) Find the minimum voltage boosting at the gate of access transistor so that storage capacitance can be charged to full 1 V supply level. Consider the role of body effect and use body effect coefficient (γ) as 0.3 V and φf = 0.35 V. (10 points) (b) Considering the constant leakage current, find the maximum refresh period that can be tolerated for the cell? If DRAM temperature rises to 350 K, what will be the new maximum refresh period that can be tolerated? (5+5 points)

Water gas is a 1:1 mixture of carbon monoxide and hydrogen gas and is called water gas because it is formed from steam and hot carbon in the following reaction: H2O(g) + C(s) ⇌ H2(g) + CO(g). Methanol, a liquid fuel that could possibly replace gasoline, can be prepared from water gas and hydrogen at high temperature and pressure in the presence of a suitable catalyst. What will happen to the concentrations of H2, CO, and CH3OH at equilibrium if more catalyst is added? (A) Catalyst will be contaminated (B) Nothing (C) Depends on the catalyst (D) Double
