ECE316_Memories

The smallest ROM memory is

• NAND ROM with implant programming

• NAND ROM with Metal 1 programming

• NOR ROM with active layer programming

• NOR ROM with contact programming

It is preferred to program the ROM using metal layers to

• reduce time to market

• reduce ROM area

• increase speed

• reduce cost

Which of the following statements is (are) correct with respect to SRAM?

• The higher the cell ratio the better

• The lower the cell ratio the better

• The higher the pull-up ratio the better

• The lower the pull-up ratio the better

Which of the following statements is (are) correct with respect to DRAM?

• 3T DRAMs require explicit capacitor

• 1T DRAMs require explicit capacitor

• 3T DRAMs read is destructive

• 1T DRAMs read is destructive

Which of the following statements is (are) correct with respect to Column Decoders?

• tree-based are slower

• pass-transistor-based are slower

• pass-transistor-based are larger in area

• tree-based are larger in area
