Samsung has begun mass production of the industry’s first 16 GB LPDDR5 memory for upcoming smartphones, such as the Galaxy S20 Ultra 5G handsets. The new DRAM devices not only offer higher capacity, but they are also 30% faster than previous-generation LPDDR4X-4266 used for previous-generation cellphones.

Samsung’s latest 16 GB LPDDR5 package consists of eight 12 Gb chips and four 8 Gb chips featuring a 5500 MT/s data transfer rate that can provide bandwidth of up to 44 GB/s. The very complex 12-device assembly is called a ‘mixed mode package’ because it contains DRAM devices that are accessed differently in different ranks. Samsung does not publish voltages of the new multi-chip 16 GB DRAM assembly, but only claims that it delivers more than 20% energy savings when compared to an 8 GB LPDDR4X package. Meanwhile, we do know that LPDDR5 memory chips feature a variable voltage that is up to 1.1 V.
