CHAPTER 5 • THE MEMORY SYSTEM PROBLEMS - Cap. 9 - Sistema di memoria 5.1 Give a block diagram similar to the one in Figure 5.10 for a 8M × 32 memory using 512K × 8 memory chips. 5.2 Consider the dynamic memory cell of Figure 5.6. Assume that C = 50 femtofarads (10−15 F) and that leakage current through the transistor is about 9 picoamperes (10−12 A). The voltage across the capacitor when it is fully charged is equal to 4.5 V. The cell must be refreshed before this voltage drops

Encoding methods and Modulation schemes 25.P.1 Computers use digital signalling‚ digitals signals are represented by the base 2 numbering system “Binary”. Binary bits are shown as 1 or 0‚ where 1 means ON and 0 means OFF. In a network where digital devices exist‚ digital signalling will be used. Dependant upon the encoding method used‚ a high voltage on a communications medium can represent a logical 1 and a low voltage of can represent a logical 0. Different methods of encoding exist these
