Contrary to what many believe, the LPDDR5 will not have any restrictions on the use of products categorized as smartphones and laptops, although it should be noted that the previous one will safely capture all the first games that developers can produce.
Therefore, the LPDDR5 is designed as a more flexible memory type, which will allow us to see it in almost all new-generation devices with limited power requirements from the following year.
LPDDR5 memory: the most important evolutionary focus of the industry
Although processors have been steadily increasing performance, storage and memory are lagging behind due to lack of consistency to develop new levels.
Fortunately, we will soon have UFS 3.1 and already in the early terminals of the market we can enjoy the memory of the LPDDR5, as happened with the Samsung S20 5G range, but what news brings it about and why was it so well received?
LPDDR5 like that is nothing more than a memory system for low power devices that should use this kind of flexible memory. As usual, it is intended to meet the operational and mobile needs of mobile phones, smartphones, tablets, laptops, and IoT devices.
Features of this type of memory
| LPDDR4 | LPDDR4X | LPDDR5 | |
|---|---|---|---|
| High speed | 4266 Mbps | 4266 Mbps | 6400 Mbps |
| Power allowed | From 4 GB to 32 GB | From 8 GB to 96 GB | Currently only 12 GB and 48 GB |
| Channels | 2 x 16 bit | 1 x 16 bit | 1 x 16 bit |
| Properties | x64 | x86 and x64 | x86 |
| Maximum, low and minimum voltage rating | 1.8V – 1.1V – 1.1V | 1.8V – 1.1V – 0.6V | 1.8V – 1.05V – 0.9V – 0.5V |
| Sector | Mobile and PC | Mobile and cars | Cell phones and cars, maybe ultra slim laptops |
First of all, it is purchased by fixing the 4, 8 or 16 banks, at speeds at any of the 800 MHz frequencies, leading to 6400 Mbps. Although version 1.0 standard has stated that they can range in size from 2 GB to 32 GB, the fact that there are manufacturers working on versions up to 96 GB for specific locations.
Another part that is often mentioned is the ability of this memory to switch between two different waveforms, all thanks to repeating the registration parameter to suit the specified frequency.
All of this provides a total bandwidth of up to 51.2 GB / s with only 1.05 volts (VDD2H, only 0.5V in VDDQ) at full operation, which means a decrease of 0.05V compared to the preceding one. and an increase in optimum performance from 4266 Gbps where it ended.
These data represent a 20% overall savings in consumption and a 50% increase in efficiency, so it is easy to understand the industry's enthusiasm to achieve this new memory.
The first modules that hit the market will be offered in a variety of formats, with the maximum size of 2020 being 48 GB at 5500 Mbps in 496FGBA packages and temperatures between 85 and 90 degrees Celsius. The introduction of EUV technology is very likely that by the year 2021 we will see the first modules reach the maximum speed established by JEDEC and the dimensions of the same size and minimum specification.
