Micron LPDDR5 RAM Officially announced; Mi 10 First to use

Micron LPDDR5 RAM Specifications

On the morning of February 6, Micron officially released the first Micron LPDDR5 RAM chip today. Micron Technology announced that it has delivered the world’s first mass-produced low-power DDR5 DRAM chip and will be the first to be shipped on the upcoming Xiaomi 10 smartphone. This also means that Xiaomi Mi 10 will become the world’s first LPDDR5 phone.

At present, Lei Jun, chairman and CEO of Xiaomi Group, vice president of Xiaomi Group, president of China, and general manager of Redmi Redmi brand Lu Weibing have forwarded relevant Weibo in succession, confirming the news.

According to reports, Micron LPDDR5 enables 5G smartphones to process data at a transmission speed of 6.4Gbps, which will effectively respond to various markets such as cars, client computers, and 5G and AI application-specific network systems for higher memory performance and lower power consumption on demand. Compared with LPDDR4x memory, LPDDR5 can reduce power consumption by more than 20%.


According to Micron Technology, 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. Using up to 6.4Gbps can achieve more than 10% endurance.

Micron said that Micron’s current LPDDR5 memory capacity shipped to customers includes 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.

  1. Multi-Bank Group architecture;
  2. Future transmission rate of 6400Mbps and bandwidth of 51.2GB / s;
  3. DVSSC & DVFSQ / WCK ultra-low power consumption technology.

Chang Cheng, vice president of Xiaomi Group, said, “We value Micron’s long-standing leadership and innovation capabilities in the memory field. Micron LPDDR5 DRAM memory has market-leading performance and brings lower power consumption to Xiaomi Mi 10 smartphones. Ensuring better performance and stability. We believe that LPDDR5 will be standard on flagship phones in 2020.”

In response, Lei Jun, founder and CEO of Xiaomi, said on Weibo that “LPDDR5, a leapfrog upgrade, has a huge impact on the improvement of smartphone performance.” Lei Jun said, “Last February, JEDEC released the LPDDR5 memory standard, which is higher than in 2014. The LPDDR4 standard has been upgraded from 3200Mbps to 5500Mbps and can transmit 44GB of data per second. LPDDR5 uses up to 16 Bank programmable and multi-clock architecture, and introduces Data-Copy and Write-X instructions to reduce power consumption, as well as links ECC error correction.”


It is reported that Micron LPDDR5 uses leading packaging technology, a single die is 12GB, the transmission rate of low-power DDR5 is up to 6.4Gbps, which is nearly twice as fast as LPDDR4, more than 20% faster than LPDDR4x, and data access speed has increased by 50%. In terms of power consumption, LPDDR5 has reduced power consumption by more than 20% compared to the previous generation. For the end user, the most direct manifestation is battery life.

In terms of performance, Micron Technology said that the previous LPDDR4 can achieve 4K and 8K applications and pictures and 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 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.

In addition, in addition to Xiaomi 10, Nubia Red Magic 5G mobile phones have also officially announced that they will be equipped with LPDDR5 memory, and the flagship may be equipped for some time in the future, it is worth looking forward to.
