Micron Technology today announced that the world's first low-power LPDDR5 DRAM chip has been mass-produced and will be used in the high-end smartphone market. The upcoming Xiaomi Mi 10 is the first mobile phone with its LPDDR5 memory, it added.
Xiaomi founder and CEO Lei Jun said on Weibo that LPDDR5 is a leapfrog upgrade and has a huge impact on the improvement of smartphone performance.
Lei Jun said that in February last year, JEDEC released the LPDDR5 memory standard, which was increased from 3200Mbps to 5500Mbps compared to the LPDDR4 standard in 2014, and it can transmit 44GB of data per second.
LPDDR5 uses a 16-bank programmable and multi-clock architecture and introduces Data-Copy and Write-X instructions to reduce power consumption and link ECC error correction, he said.
Micron's LPDDR5 single die is 12GB, and the transmission rate of low-power DDR5 is up to 6.4Gbps, which is nearly twice as fast as LPDDR4 and more than 20% faster than LPDDR4x.
Compared with the previous generation, LPDDR5 has reduced power consumption by more than 20%.
For users, the most direct feeling is endurance. Micron Technology claims that because LPDDR5 runs faster, the App processor and operation speed are faster, so that terminals equipped with LPDDR5 will have a 5% -10% extension of the battery. If you use the highest 6.4Gbps version, you can achieve more than 10% battery life extension.
Micron said that the previous LPDDR4 can achieve 4K, 8K applications and pictures, picture editing. In addition, if LPDDR4 runs 100 apps at the same time, a bottleneck may appear, which is more than enough for LDRR5.
Micron's current LPDDR5 memory capacities include 6GB, 8GB, and 12GB, with data transfer rates of 5.5Gbps and 6.4Gbps. Micron will also apply LPDDR5 memory to mid- to high-end smartphones through UFS-based multi-chip packaging (uMCP5) in the first half of 2020.
The multi-chip package LPDDR5 can extend battery life and provide higher bandwidth to support high-performance image processing functions previously only available on flagship models.
Micron believes that mobile phones equipped with LPDDR5 in the first half of this year will focus on 8GB and 12GB of memory, but the flagship mobile phone's memory is expected to increase to 16GB in the second half of the year.
