Samsung Electronics' Mobile eXperience (MX) division expressed apprehensions in August regarding the supply delay of 1b nm (around 12nm) LPDDR memory samples intended for the development of the Galaxy S25 series. The company initiated mass production of 1b nm process 16Gb DDR5 memory in May 2023 and subsequently launched 1b nm 32Gb DDR5 in September of the same year, actively progressing the internal development of 1b nm LPDDR mobile memory products.

In June, the Korean media outlet had already cited that the yield rate of Samsung's 1b nm DRAM memory products was less than 50%. The recent report emphasizes that the DS division was expected to supply a significant number of 12Gb and 16Gb capacity 1b nm LPDDR memory samples to the MX division by August for the Galaxy S25 series. However, the DS division failed to provide the required quantity of samples on time.

According to insiders, the yield rate of Samsung's 1b nm LPDDR memory did not meet expectations, impacting the internal supply schedule. The MX division has reportedly lodged a protest and is currently reevaluating the DRAM supply plan for the Galaxy S25 series. Generally, for stable and economical mass production and supply in the DRAM industry, a memory yield rate of at least 80% is necessary. The current situation suggests that Samsung's 1b nm LPDDR memory yield rate is significantly below this target, even for internal supply, indicating substantial issues that need to be addressed.
