Samsung Announces First LPDDR5 DRAM Chip, Targets 6.4Gbps Data Rates & 30% Reduced Power

[Samsung] is announcing that they have completed fabrication, functional testing, and validation of a prototype 8Gbit LPDDR5 module. The company is targeting data rates up to 6.4Gbps-per-pin with the new memory, and while Samsung isn't ready to start mass production quite yet, the company's press release notes that they're already eyeing it.

[...] In terms of performance, Samsung is targeting up to 6.4Gbps/pin with the new memory. Which for a typical 32-bit bus chip works out to 25.6GB/sec of memory bandwidth. This is a 50% increase in bandwidth over the current LPDDR4(X) standard, which tops out at 4.266Gbps under the same conditions. So for a high-end phone where 64-bit memory buses are common, we'd be looking at over 50GB/sec of memory bandwidth, and over 100GB/sec for a standard 128-bit bus PC.

Samsung Commences Mass Production of First Ever 12Gb LPDDR5 DRAM for Premium Handsets

After the LPDDR4X standard, Samsung is ready to take mobile computing to the next plateau, as the Korean giant has announced that mass production of the industry's first 12-gigabit (Gb) LPDDR5 mobile DRAM, a component that has been optimized for 5G and AI features for future smartphones.

Additionally, Samsung plans on mass producing 12-gigabyte (GB) LPDDR5 packages later this month, which each package combining eight of the 12Gb chips. This reveals that future premium devices will demand the best when it comes to faster, more efficient memory, and Samsung wants to be ahead of the curve in both supply and demand.

Data rate will be 5,500 MT/s, compared to 4,266 MT/s for LPDDR4X, with up to 30% less power consumption than LPDDR4X. Future LPDDR5 chips could hit 6,400 MT/s.

Samsung plans to start producing 16Gb LPDDR5 chips next year. Smartphones with 16 GB of DRAM are sure to follow.

Samsung Starts Mass Production of Second-Gen 16GB LPDDR5 RAM for Future Premium Smartphones

Samsung has announced that it will kick off mass production of the world's first 16GB LPDDR5 RAM package for future smartphones. Last year, the Korean giant stated that it started mass production of 12GB LPDDR5 RAM. For 2020, Samsung has taken that production dial to the next phase and claims that the new RAM packages will enable users to experience enhanced 5G and AI features ranging from graphic-rich gaming and smart photography.

According to the company, the data transfer rate for the 16GB LPDDR5 [package] is 5500Mb/s (megabits per second), making it significantly faster than the previous-generation LPDRR4X RAM package, which peaks out at 4266Mb/s. That's not the only benefit of using these chips, because compared to an 8GB LPDDR4X package, the new mobile DRAM can deliver more than 20 percent power savings while offering twice the memory capacity.

16 GB DRAM packages could also be used in single board computers and other compact systems. For example, the BCM2711 SoC used in the Raspberry Pi 4 Model B can theoretically address up to 16 GB of memory.

Samsung Announces LPDDR5X DRAM for Smartphones; 1.3x Faster Than LPDDR5 With Speeds up to 8.5Gbps

Samsung today officially announced LPDDR5X DRAM chips for smartphones and other applications. Compared to the LPDDR5 standard, the new chips bring increased speeds, and it will be no surprise that we will see them in action in several 2022 flagship handsets.

[...] In contrast to LPDDR5's 6.4Gbps maximum bandwidth, LPDDR5X can achieve 1.3-times the performance with processing speeds that go up to 8.5Gbps. Samsung has used its 14nm technology to mass produce the next-generation DRAM chips, and it will be advantageous for portable devices too because the new standard is 20 percent more energy-efficient than LPDDR5.

The press release says that 16Gb LPDDR5X chips will enable 64 GB memory packages, "accommodating increasing demand for higher-capacity mobile DRAM worldwide." In other words, Samsung is planning to put 32 dies in a single package, and eventually stick 64 gigabytes of memory in smartphones (or tablets, or laptops). Recently, Samsung has been making 16 GB packages with only 12 or 8 dies:

The 16Gb LPDDR5 can build a 16GB package with only eight chips, whereas its 1y-based predecessor requires 12 chips (eight 12Gb chips and four 8Gb chips) to provide the same capacity.
