Many people may have wondered why devices need more RAM because most times the RAM space is underutilised. With the advancement of Artificial Intelligence, the arrival of 5G and the release of new processing chips one might need a rethink and accept that FASTER and MORE memory is what we need. That is what Samsung is thinking too, I guess.
Device and OLED screen makers Samsung Electronics has announced its latest 10nm class 8-gigabit (Gb) LPDDR5 DRAM. In 2014 Samsung brought the first 8Gb LPDDR4 to mass production, and since then it has been setting the stage to enable the transition to the LPDDR5 standard. The DRAM is made to be used in upcoming 5G, and artificial intelligence (AI) powered mobile applications.
“The newly-developed 8Gb LPDDR5 is the latest addition to Samsung’s premium DRAM lineup, which includes 10nm-class 16Gb GDDR6 DRAM (in volume production since December 2017) and 16Gb DDR5 DRAM (developed in February),” the company disclosed.
Samsung’s new 8Gb LPDDR5 boasts an incredible data rate of up to 6,400Mb/s, which is about 1.5 times as fast as the DRAM chips used in most current flagship mobile devices (LPDDR4X, 4266Mb/s). With the increased transfer rate, the new LPDDR5 can send 51.2GB of data, or approximately 14 full-HD video files measuring 3.71GB each, in a second.
The Samsung 10nm-class LPDDR5 DRAM would be available in two bandwidths – the 6,400Mb/s bandwidth at a 1.1 operating voltage (V) and the 5,500Mb/s operating at 1.05V – making the chip the most versatile mobile memory solution for the next-generation of smartphones and automotive systems.
This new performance advancement was made possible through several architectural enhancements. By doubling the number of memory banks from eight to sixteen, the new memory chip can attain a much needed higher speed while also reducing the power consumption thus preserving battery life. The 8Gb LPDDR5 is also designed to make use of a highly advanced, speed-optimised circuit architecture that verifies and ensures the chip’s ultra-high-speed performance, Samsung noted.
To maximize the power savings, the 10nm-class LPDDR5 was engineered to lower its voltage in accordance with the operating clock speed of the corresponding application processor, when in active mode. It also was configured to avoid overwriting the cells with ‘0’ values.
In addition, the new LPDDR5 chip will offer a ‘deep sleep mode’, which cuts the power usage to approximately half the ‘idle mode’ of the current LPDDR4X DRAM. Thanks to these low-power features, the 8Gb LPDDR5 DRAM will deliver power consumption reductions of up to 30%, maximizing mobile device performance and extending the battery life of smartphones, Samsung said.
Based on its industry-leading bandwidth and power efficiency, the LPDDR5 will be able to power AI and machine learning applications, and will be UHD-compatible for mobile devices worldwide, the company continued.
Samsung, together with other leading global chip vendors, has completed the functional testing and also validation of a prototype 8GB Samsung said it plans to begin mass production of the next-generation DRAM lineups (LPDDR5, DDR5 and GDDR6) in line with the demands of global customers.
We expect faster devices, and hopefully, they will start working on a faster ROM.
