Samsung Is Accelerating Development Of LPDDR6 RAM In H2 2025 To Obtain A Lead Against Chinese Manufacturers, Qualcomm Will Be One Of The First To Adopt This Technology
Jun 6, 2025
China’s Innovative Memory Technology (CXMT) is aggressively attempting to narrow the technological gap between it and Samsung by having completed the development phase of LPDDR5X RAM. This update must have sent alarm bells running through Samsung’s memory division because the latest report states that the Korean giant has gone into overdrive mode in developing its next-generation LPDDR6 memory chips, which are said to deliver more bandwidth while consuming less power.
The newer LPDDR6 RAM standard is said to be mass produced on Samsung’s ‘1c DRAM,’ ensuring that the company gains a meaningful edge against Chinese rivals
A report from Business Post that was spotted by the tipster @Jukanlosreve mentions that CXMT has already commenced the development of LPDDR6 RAM chips this year, with industry watchers speculating that the Chinese manufacturer could start full-scale production as early as 2026 at its current pace. Not wanting to get left behind, Samsung has accelerated development of its own LPDDR6 RAM technology, with the advantage being that the memory chips will be fabricated on the company’s advanced 1c DRAM process.
Mass producing memory chips on the aforementioned architecture should give Samsung a meaningful edge over Chinese players. LPDDR6 RAM is expected to be a vital component in a variety of applications, including AI, mobile computing, robotics, and self-driving cars. Mass-producing DRAM is categorized under various technologies, with ‘1x’ being the first iteration and ‘1c’ being the sixth generation. With each passing generation, companies can scale past certain performance and efficiency ceilings.
Qualcomm will reportedly be the first customer to incorporate Samsung’s LPDDR6 RAM chips to its products, with its upcoming Snapdragon 8 Elite Gen 2 rumored to have immediate support for this technology, with the SoC expected to be unveiled during the Snapdragon Summit, which will be held from September 23 onwards. No other potential customers are mentioned in the report, but looking at the benefits of LPDDR6 RAM, it should not be long before other clients begin placing orders, giving Samsung a notable lead over CXMT.

If ever samsung develop it, will they be allowed to sell the latest to CN?
Take a guess, with uncle Sam getting more paranoid about China, you really think they will allow that? Lmao.
Texas instrument MCU , the popular C2000 unlike most other suppliers using ARM or RISC general architecture, is using DSP +general MCU instead which gives it an advantage in real time control and much quicker response time.
Are there any domestic suppliers provide DSP + general MCU based MCU.

What do you mean by "general MCU". All MCU's use some sort of ISA. C2000 uses TI's proprietary ISA. Both ARM and RISC-V also has ISA profiles optimized for MCUs. IMHO, the underlying ISA doesn't matter much as long as the tools for programming it are available. What matters more are how good the on-chip realtime peripherals and interfaces are.
General MCU uses general registers internally and DSP uses floating point registers specialized in floating point calculation.
ISA is the bus.
By ISA I meant Instruction Set Architecture, not the bus. As in x86, ARM, RISC-V, MIPS, etc. Texas Instruments also has it's own proprietary Instruction Set Architecture (which you are referring as General MCU). They have ARM MCUs too. You seemed to imply a latency disadvantage for MCUs that use ARM/RISC-V ISA. My point was that has less to do with it being ARM/RISC-V but rather differences in the performance of onboard realtime peripherals, DSP implementation etc. ISAs are just a means of programming it for the developers.
It's the same for ARM/RISC-V MCUs that has DSP.

ARM/RISC MCU uses 32 bits register. This is as high as general MCU would go. There are also 8bits and 16 bits MCU
DSP registers can be 80 bits long.
