LPDDR4 came two years after the previous LPDDR3 had done so successfully and has so far been the shortest version of memory time within JEDEC standards.
Improvements that led to LPDDR4 were significantly greater in terms of performance, but left much to be desired following a reduction in usage, as there was no fluctuation in this. Therefore, devices made with this type of memory have not shown how autonomy increases as it is, which in mobile devices is important in practical times.
LPDDR4X: a descriptive step for new generation memory
An active jump in performance may not make it clear in the eyes of developers and companies the acceptance of such a win rate for their products. Therefore, LPDDR4 was not a step many would like to take in all product categories and is restricted to high end.
LPDDR4X comes as a memory that can be LPDDR4 and will provide more features than:
- Until 12 GB per pack
- Zoom in to work by + 15%.
- Use reduced power to -17%.
- Hurry up 4266 Mbps
- Extended skills
- High temperature to 85 ° C.
- Cost reduction
As we can see, all the benefits over LPDDR4, where in addition, depending on the manufacturer, this data may be different, because its unique lithographic processes make a huge difference in this respect.
Energy management and limiting its use are important
The LPDDR4X will come and give life to mobile devices, which require greater autonomy for their batteries. On a PC this kind of memory was completely useless due to the low bandwidth it offers compared to current systems, where we also do not need development of much use as provided by this type of memory and the industry is not compatible with that. , because it is mounted on a plate.
Development is therefore focused on two important factors, the operating voltage and the reserve strength, which are linked to the input and output voltage.
Active or active power is what is produced when the device is 100% charged, and it is very limited when used, because it drains the battery very quickly and efficiently. Therefore, it will cause the temperature to rise and deteriorate more rapidly.
Reducing the use of this power transmission helps extend battery life, just like a smartphone, so the benefit is not limited to specifications.
The waiting power is one that eliminates the memory when the phone is positioned, that is, in the lounge. This is important as most devices are turned off almost all the time. To achieve two-way reductions in use, JEDEC introduced a significant improvement: significantly reducing the use of LPDDR4X.
Approximately 50% of the force is less than the same speed
While descriptive information is open to manufacturers, JEDEC assures that at the same speed it is able to achieve a 50% reduction in reference power. LPDDR4 operates on average at 1.12V power, and LPDDR4X will work on it 0.61V.
This, among other features and specifications, makes both types of memory incompatible, so manufacturers will have to adjust their composition to include these new memory modules. So when you read some details they will have to explain to them what kind of LPDDR they are using, because as we have seen the difference shown is quite impressive.
As if that isn't enough, giants like Samsung are announcing that they can increase the performance of these memories under their new manufacturing process to 10 nm and raise electricity 1.8V and 125 ° C at its highest temperatures. What they have not yet specified is the speed they would have achieved with these components, but it is more than close to the 5000 Mbps achieved by the new LPDDR5, or trial.
