According to South Korea’s MoneyToday, SKhynix is currently developing another variant of LPDDR5. The large supplier of DRAM and flash memory chips has publicly revealed its LPDDR5 Turbo(T) design, dating back to late 2023, with the iteration billed as "the world's fastest mobile memory standard."
The first public demonstration of LPDDR5T (10533) took place at the IEEE Solid-State Circuits Conference last February. Currently, the familiar LPDDR5X standard is very common in commercial channels.
Industry insiders believe that the unannounced LPDDR5M standard operating voltage is lower (allegedly 0.98V) compared with current products (X: 1.05V). Given the nature of its acronym, LowPowerDoubleDataRate, this memory type was originally designed to operate efficiently and is ideal for mobile applications.
One industry insider noted that internal company discussions highlighted a key percentage difference: "At top speed, LPDDR5M is approximately 8% more energy efficient than LPDDR5X." A recent MoneyTodaySK-related news report mentioned that the old LPDDR4 standard was classified as a "legacy product" by the company's leadership. In contrast, the LPDDR5 variant is (allegedly) classified as a "high value-added product".
Memory industry observers believe that the rumors of LPDDR5M are a strengthening (and diversification) of SKhynix's strategy, which already includes LPDDR5X and LPDDR5T. According to sources, LPDDR5M memory is destined to appear in next-generation smartphone devices with onboard artificial intelligence capabilities.
