If WL is the Word Line and BL the Bit Line, an SRAM cell is shown in Correct Answer <img alt="F1 S.B 15.7.20 Pallavi D201" src="//storage.googleapis.com/tb-img/production/20/07/F1_S.B_15.7.20_Pallavi_D201.png" style="width: 271px; height: 204px;">

SRAM (Static Random Access Memory) Cell:

  • It can store the information as long as the power is applied.
  • Random Access means that in an array of SRAM cells each cell can be real or written in any order.
  • The structure consists of 6 transistors to store 1-bit information.
  • The main structure is formed by two cross-coupled inverters, where the output of each inverter is fed input to the other inverter as shown:

  • WL – Word line
  • BL – Bit line
  • WL & BL are used to read and write from or to the cell.

Study the information carefully and answer the questions given below: If we arrange the alphabets in the word "RATE" in the English alphabetical order, word "AERT" is formed. Then the third alphabet from the left in this word is "R". similarly, from the word "OPEN" we get - "ENOP" and the third alphabet from the left is "O". From the word "CHEF" we get - "CEFH" the third alphabet from the left "F". From the word "TOY" we get - "OTY" and the third alphabet from the left is "Y". From the word "EAT" we get - "AET" and the third alphabet from the left is "T" If we use all these letters, then a meaningful English word "FORTY" can be formed. Now find which of the following word set DOES NOT give a meaningful word in a similar way.
The shift register shown in the figure is initially loaded with the bit pattern 1010. Subsequently, the shift register is clocked, and with each clock pulse the pattern gets shifted by a one-bit position to the right With each shift, the bit at the serial input is pushed to the leftmost position (MSB) After how many clock pulses will the content of the shift register become 1010 again?

A solid-oxide fuel cell is fed with carbon monoxide and reacts with air to produce CO2. This reaction will produce 2 electrons which are used to power an electric circuit external to the fuel cell. The reaction equation is shown below: 2CO(g) + O2(g) -> 2CO2(g) ΔHr° = -565.96 kJ/mol This reaction does not occur for other types of fuel cells which use a catalyst, such as polymerelectrolyte membrane or phosphoric-acid fuel cells. The presence of carbon monoxide on the anode side of these types of fuel cells will cause catalyst poisoning, reducing the efficiency and voltage of the fuel cell. Determine the rate of enthalpy change for a carbon dioxide production rate of 208 mol/hr. The extent of the reaction occurring in the fuel cell can be obtained by the following equation: where:
