What is the energy cost associated with reading data from Flash memory?

The energy cost of reading data from Flash memory is typically measured in nanoamp-hours (nAh) per byte. Understanding the specifics of Flash memory operation reveals that the reading process is usually less energy-intensive compared to writing or erasing operations.

Option A states that the energy cost is 1.1 nAh per byte. This figure is a realistic representation of the energy expended during read operations. Flash memory's design allows it to read data efficiently, utilizing relatively minimal energy compared to other operations such as writing, which tends to consume more significant power due to the need for electron movement within the memory cells.

The values associated with the other options are not commonly reflective of the standard energy requirements discovered in practical applications or scholarly resources about Flash memory. While higher values like 83.3 nAh per byte suggest an energy cost that does not align with typical performance metrics for reading, lower values such as 0.5 nAh might underestimate the realistic consumption encountered during read operations.

In summary, the statistic provided in Option A reflects a reasonable approximation of the energy cost for reading data from Flash memory, emphasizing the efficiency of such operations in this type of memory architecture.
