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 [samsung.com] 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 [samsung.com]:
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.
