Micron Technology has been quiet about the progress with LPDDR4, a next generation memory standard for mobile devices. But the company may actually be the first supplier to ship commercial LPDDR4 products to its customers since the company has been sampling LPDDR4 memory with designers of mobile system-on-chips for quite some time.
“We are the first supplier to sample low-power DDR4 to our customers and chipset partners. This allows them to debug their next-generation systems and reference platforms with Micron solutions,” said Mark Adams, the president of Micron, during a conference call with financial analysts earlier this week.
Late in December, 2013, both Samsung Electronics and SK Hynix said they had started to sample LPDDR4 memory with developers of mobile application processors. The companies indicated that the first LPDDR4 products came in 8Gb capacity, operated at 3200Mb/s effective data-rate and featured ultra-low voltage of 1.1V.
While Micron did not indicate any technical details about its LPDDR4 memory chips that are currently tested by companies like Apple or Qualcomm, it is likely that they are similar to competing solutions (3200MHz effective frequency, 8Gb capacity, 1.1V voltage) and are compliant with preliminary specification of the upcoming memory standard.
The new interface LPDDR4 is expected to be loaded onto flagship mobile devices at the end of 2014 and is anticipated to be commercialized regularly from 2015. Finalized standard of the LPDDR4 specification is expected to be agreed on later this year. LPDDR4 will become a mainstream memory type for mobile devices starting from 2016.
Some memory market analysts believe that the demand for LPDDR types of memory for portable electronics will exceed that for traditional DDR DRAM for personal computers in 2014.
