Micron has announced their first LPDDR5 DRAM is in mass production and now shipping to customers. The new RAM is significantly faster and more power efficient than LPDDR4x. One of the first products to use the new LPDDR5 will be the upcoming Xiaomi Mi 10 smartphone.
Micron’s LPDDR5 is available in 6GB, 8GB and 12GB packages, with speeds of 5.5Gbps and 6.4Gbps per pin. The faster speed grade is a 50% improvement over their fastest LPDDR4x products (4266Mbps per pin), and Micron also claims better than 20% reduction in power use compared to LPDDR4x. Micron will also soon be offering multi-chip packages pairing LPDDR5 with UFS-based flash storage; these products will be available sometime during the first half of the year.
The most visible applications for LPDDR5 will be this year’s crop of flagship smartphones, but Micron is also targeting automotive and networking applications with the obligatory references to 5G and AI driving demand for faster memory.
