The float zone wafer has the lowest oxygen levels of the semiconductor types. The method used to create these wafers also minimizes surface defects. Float zone wafers have higher conductivity and can perform well in high-speed data applications like computer memory.
However, first, it’s essential to understand what a computer memory chip does and how semiconductor technology makes its function possible. This way, we can understand why the float zone wafers may be ideal for this niche.
Memory chips consist of rectangular integrated circuits placed on a silicon wafer. These memory units store any volatile data into metal oxide semiconductor cells inside each integrated circuit block. Semiconductor technology takes electricity from the power supply unit and provides the conductivity needed to retain the energy.
There are currently two types of memory chips used in computers and other electronic devices. These are the RAM or Random Access Memory and the ROM or Read-Only Memory.
The ROM is a permanent storage medium for computers and their system peripherals. The data within these ROMs cannot be overwritten or replaced. They contain code that tells the computer’s parts what function to perform.
You can also consider ROMs as “non-volatile memory.” Unlike RAM, ROMs retain their embedded data even if there is no power.
RAM is volatile memory and is the direct opposite of ROM. RAM chips take live data from the computer to perform processes and code that information to a file on the hard drive. The central processing unit continually refreshes the RAM storage to prioritize active tasks. The RAM becomes full if you run too many programs, and the computer slows down.
RAM automatically loses all data when the chips lose power.
Dynamic RAM, or DRAM, chips store electrical power into capacitors. These capacitors discharge periodically, at which point the memory chips also refresh the electronic information they contain.
Unlike DRAM, static RAM does not need refresh cycles to update its data. SRAM can read and write data faster than DRAM. However, this memory chip also consumes more energy.
Its lower oxygen levels and minimal surface defects make the float zone wafer more efficient than wafers produced using other technologies. Contact us now and learn more about this semiconductor product.
