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

INTRODUCTION The Babylonians used a sexagesimal (base 60) numeral system to make astronomical calculations‚ from which the use of 60 seconds in a minute and 60 minutes in an hour is derived. I will research how the Babylonians used this system to measure time. I have chosen the topic Babylonian time system as it relates history and math. I find it fascinating how in the past‚ people had to come up with elaborate theories and intricate systems from scratch‚ as compared to how modern day mathematicians
