Innosilicon has reportedly started shipping its LPDDR6 memory modules, which offer an impressive speed of 14.4 Gbps. This is significantly faster than Samsung's initial LPDDR6 modules, which achieve data rates of 10.7 Gbps. Innosilicon's modules provide a 1.5x increase in IO speed capability compared to the 9.6 Gbps of LPDDR5X that the company previously offered, and they significantly enhance efficiency. The latest LPDDR6 also increases the number of bits per byte of IO from 8 bits to 12 bits. This results in LPDDR6's bandwidth at a single-channel 24-bit I/O speed being twice that of LPDDR5X at a 16-bit single-channel. The company has reportedly prepared collaborative manufacturing with TSMC and Samsung to secure sufficient capacity for LPDDR6 IP production.
As one of the leading LPDDR6 implementations, this move directly challenges competitors like Samsung, SK Hynix, and Micron, who are also presenting their LPDDR6 solutions to customers but are not eager to ship much of the capacity early in the LPDDR6 lifecycle. Additionally, the JEDEC specification lists LPDDR6 running at a maximum speed of 14.4 Gbps per pin, which Innosilicon has aimed for from the start. This contrasts with Samsung's approach , which has developed 10.7 Gbps LPDDR6 memory on a 12 nm node, peaking at the same speed as its earlier LPDDR5X. However, Samsung emphasizes power efficiency as the main selling point of these early modules, claiming a 21% improvement in energy efficiency over its predecessor. It remains to be seen which IP customers will choose, and the availability of off-the-shelf modules will certainly influence the final decision.
