Furthermore, the energy efficiency of 8Gb LPDDR5 with 10nm process is higher. LPDDR5 DRAM can work under two kinds of bandwidth, among them the working voltage is only 1.1v at 6400Mb/s transmission rate, and the working voltage is lower 1.05v at 5500Mb/s rate. At the same time, the number of memory 'modules' (sub-units in DRAM cells) has doubled from 8 to 16, and the new memory can achieve higher speeds while reducing energy consumption. Samsung said, “8Gb LPDDR5 also uses an extremely advanced and speed-optimized circuit architecture to verify and ensure the ultra-high-speed performance of the chip. In order to maximize power saving, 10nm-class LPDDR5 is designed to reduce its voltage in active mode. In order to be consistent with the working speed of the corresponding application processor, and it is also configured to avoid overwriting the unit with a value of '0'.' I believe that most mobile users are not unfamiliar with the memory parameters of mobile phones. Since last year, most mobile phones All have been upgraded from LPDDR4 to LPDDR4X memory, including Apple’s iPhone 8 series and iPhone X. Therefore, it is obvious that the next-generation memory is LPDDR5 in accordance with the changing rules of the naming method. So, when will the new generation of mobile phone memory LPDDR5 arrive? The official answer from Samsung, a major memory technology company, is 'almost.' On July 17, Samsung officially announced that it has successfully developed the industry's first 10-nanometer (nm) grade 8 gigabit (Gb) LPDDR5 DRAM. This is Samsung's another high-end DRAM product after mass production of the first 8Gb LPDDR4 in 2014, mass production of 16Gb GDDR6 DRAM in December 2017, and the development of 16Gb DDR5 DRAM in February 2018. Samsung said, 'The newly developed 8Gb LPDDR5 represents a major advancement in low-power mobile memory solutions.' The Chinese name of LPDDR5 is 'five generations of low-power double data rate synchronous dynamic random access memory.' According to Samsung, first of all, 8Gb LPDDR5 has a significant increase in data transmission speed, with a data transmission speed of up to 6400 Mb/s. Samsung claims that thanks to the increase in transmission speed, the new LPDDR5 can send 51.2 GB of data per second, which is approximately equivalent to 14 1080p Full HD video files (each file is 3.7 GB). In addition, LPDDR5 DRAM also provides a deep sleep mode. It is said that the power consumption is reduced to about half of the power consumption of the current LPDDR4X DRAM in the “idle mode”. In general, 8Gb LPDDR5 DRAM not only has higher bandwidth and faster speed, but also The current flagship mobile device (LPDDR4X, 4266 Mb/s) uses 1.5 times the speed of the mobile DRAM chip, and the power consumption is reduced by up to 30%, which improves the performance of the mobile device and also extends the battery life. When will LPDDR5 memory be produced? What? Samsung did not disclose the specific mass production time, only that it has completed the functional testing and verification of the prototype 8GB LPDDR5 DRAM package (consisting of eight 8Gb LPDDR5 chips), so it may have to wait for a certain time. Considering Samsung It is one of the suppliers of Apple iPhone mobile phone memory (the others are SK Hynix Hynix and Micron Micron). In the future, a certain generation of iPhone will soon adopt Samsung’s LPDDR5 memory. By then, the iPhone’s memory speed will be faster and more efficient. The actual iPhone experience will also perform faster and save more power. Of course, other flagship phones other than Apple will also follow up LPDDR5 memory, but considering that the cost of mobile device parts created by new technologies is usually higher, it is truly the first The mobile phone products that use LPDDR5 memory are either Samsung’s own Galaxy S series or Apple’s iPhone. However, the JEDEC organization that specifies memory standards so far has not announced the relevant specifications for LPPDDR5 or even DDR5 memory, so the time to wait may be It takes longer than expected.
