What factors determine the NAND-type flash memory?

 

Manufacturing Process

Manufacturing process can affect the density of transistors, but also affect some operations of the time. For example, the aforementioned stability and time stability of time to write, they account for our calculations were an important part of time, especially when writing. If we can reduce these times, we can further improve performance. 90nm manufacturing process can improve performance? I'm afraid the answer is! The current reality is that as storage densities increase, the need to read, write settling time is an upward trend. Previous calculation in the example of this trend is reflected, or 4Gb chip performance more evident.

 

 

 

On the whole, large-capacity NAND-type flash memory chips While addressing, the operating time will be slightly longer, but with the increased page capacity, the effective transmission rate of still larger, high-capacity chip with the market for capacity, cost and performance demand trends. The increase in data lines and increase the frequency, it is the most effective way to improve performance, but because of the command, address information takes the operating cycle, and some fixed operating time (such as signal settling time, etc.) and other technology, physical factors, they do not bring an improvement in performance.
