Chip main memory are not null
Web@Neil: a null pointer constant (prvalue of integer type that evaluates to zero) is convertible to a null pointer value. (§4.10 C++11.) A null pointer value is not guaranteed to have all bits zero. 0 is a null pointer constant, but this doesn't mean that myptr == 0 checks if all the bits of myptr are zero. – WebJun 16, 2015 · 64. Modern CPUs are very fast compared to all things external, including memory (RAM). It is understandable, since CPU clock frequency has reached a point where it takes several clock ticks for an electric signal simply to run from from the CPU through the bus to RAM chips and back. It also complicates life on many levels: multi-level cache ...

Web3% and the hit time is 2 CCs. The processor also has an 8 Mbyte, on-chip L2 cache. 95% of the time, data requests to the L2 cache are found. If data is not found in the L2 cache, a request is made to a 4 CCs to process a memory request. How often is data found in main memory? Average memory access time = Hit Time + (Miss Rate x Miss Penalty) http://arsenalfc.stanford.edu/publications/hydra_dramws.pdf
WebThis type of memory, also called main memory or RAM (Random Access Memory), is only used for temporary storage of data. When you restart a computer, it typically wipes the memory entirely. Memory wouldn't be a good place to store data for later, like files and programs. Computers store long-term data in a different type of memory: external ...
