In asserting its first quarter leads to 191, SK Hynix introduced that it intends to extend the manufacturing of DRAMs produced with its first 10nm (1X nm) manufacturing course of and promote DRAMs shall be manufactured within the second half of this yr utilizing the second era manufacturing expertise of the 10 nm class (also referred to as 1Y nm). The accelerated transition to 10nm applied sciences will allow the corporate to extend DRAM bit output, in the end reducing prices and getting ready for next-generation storage.
The primary merchandise manufactured utilizing SK Hynix '1Y-nm manufacturing expertise are the 8GB DDR4-3200 reminiscence chips. The producer stated the brand new course of would enable it to shrink the chip measurement of an 8Gb DDR4 machine by 20% and scale back its energy consumption by 15% in comparison with an identical machine manufactured utilizing its 1X nm manufacturing expertise , As well as, SK Hynix 'new 8GB DDR4-3200 chips provide two key enhancements: a Four-phase clocking scheme and Sense Amplifier Management expertise. Four-phase clocking will increase sign energy to make sure stability at excessive information charges. In the meantime, the SAC reduces the chance of knowledge errors that may happen because the transistor measurement turns into smaller.
Whereas these applied sciences will proceed to be related to DDR4 this yr, SK Hynix is reportedly utilizing its 1nm manufacturing course of to supply DDR5, LPDDR5, and GDDR6 DRAMs. Due to this fact, it’s essential for the corporate to arrange the 2nd era 10nm era expertise for the long run as shortly as doable. As well as, SAC will even be related to next-generation course of applied sciences.
The transition from SK Hynix to DRAM 10nm manufacturing applied sciences was fairly sluggish. Micron and Samsung have been delivering merchandise utilizing the second-generation 10nm class since 2018, whereas till not too long ago, SK Hynix contended with the first era of the 10nm class for DRAMs. It now seems to be as if SK Hynix's second era manufacturing expertise within the 10 nm class shall be used for business merchandise within the second half of 2019.
