14 DAY TRIAL // Korean giant corporation Samsung has just announced that it started manufacturing 4Gb memory chips using 20nm manufacturing technology, on its official website. Remember that you need two such 4 Gb memory chip to have 1 GB of LPDDR2 RAM in you smartphone, as 1 GB (Gigabyte) is equal to 8 Gb (Gigabits).
Up until now, Samsung has been using four chips manufactured in the 30 nm technology process to obtain a 2 GB memory chip and, as such, mobile devices like smartphones with such a memory were hard to find.
By using the 20 nm manufacturing process, Samsung can now build 2 GB multi-layer memory chips that are just 0.8 millimeters thick. This is approximately 20% thinner than a 4-stack of 30 nm memories.
Starting mass production on the 20 nm manufacturing line means that the availability of such thin and modern chips is going to increase sharply in the following period.
As we previously explained, going for a smaller manufacturing process not only offers the chip builder products that use less power and work at higher frequencies, but it also allows for a greater production at much better costs.
When shrinking a chip design from 30 nm to 20 nm, the manufacturer will obtain a much larger number of chips out of the same silicon wafer.
So, the price of the chip is going down, the availability increases, the power consumption is lower or the same when clocking the memory chips at 1066 MHz and the thickness is reduced.
These factors and a sum of others as well will lead to an increase in the number of mobile devices sporting a 1066MHz fast 2 GB or LPDDR2 memory.
