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

On rare occasion‚ a cache may need repairs‚ or be temporarily inaccessible because of construction‚ weather‚ hunting‚ or any other peculiar reason. In this case‚ it will be labeled online as disabled. Disabled caches are marked like this to signal that they are inactive for the time being. Therefore‚ no one will go looking for a missing cache.

columns from the transformations. By not removing the unwanted columns‚ the cache size will increase. 1.2. Size of the source versus size of lookup Let us say‚ you have 10 rows in the source and one of the columns has to be checked against a big table (1 million rows). Then PowerCenter builds the cache for the lookup table and then checks the 10 source rows against the cache. It takes more time to build the cache of 1 million rows than going to the database 10 times and lookup against the
