7 month 15 day ,JEDEC Solid state storage Association officially released DDR5 SDRAM Memory standard specification , It's open PC The prelude to a new era .

   According to the specification ,DDR5 Frequency of memory ( Data transmission rate ) The starting point is DDR4 Standard limit 3200MHz, And the highest can be achieved
6400MHz, According to the Convention, the actual product will be much higher than this level , At the same time, the voltage changes from 1.2V Further reduced to 1.1V, And single Die The capacity of 8-32Gb (1-4GB).

   today , Korean storage giant SK Hynix announced , Official release of the world's first DDR5 Memory , frequency , capacity , Energy efficiency and functional technology have reached a new height .

  SK Hynix started DDR5 Memory modules are server oriented , Data center RDIMM form , be based on 1Ynm Process made 16Gb grain , Single capacity 64GB, With the help of
TSV Silicon perforation technology , Up to 256GB.

   In terms of frequency, the starting point is 4800MHz, Up to 5600MHz, It's equivalent to one second of transmission 9 Full HD movies .

   The voltage is standard 1.1V, Reduce power consumption 20%.

   Since it is RDIMM Memory module , Natural embedded support ECC error correction , even if it is 1 Bit errors can also be corrected by themselves , Application reliability is called to improve 20 times .

   The timing has not been announced ,JEDEC In the specification DDR5-4800 Corresponding to three timing specifications , namely 34-34-34,40-40-40,42-42-42.

   What's interesting is that ,Intel At the same time SK Hynix's DDR5 Memory endorsement , He stressed the close cooperation between the two sides .

   According to the roadmap ,Intel Next generation server platform Sapphire Rapids Will be the first to support DDR5 Memory , Support at the same time PCIe 5.0 Bus ,CXL
1.1 Heterogeneous interconnection protocol and so on , And continue Intel Built in AI acceleration strategy of , Support the latest “ Advanced matrix expansion ”(AMX) accelerate ,2021 Delivery started in the second half of .

   As for the consumption platform , At the end of next year or the first half of the following year Alder Lake 12 Dai coolie is expected to start support DDR5, Maximum frequency 4400MHz, Maximum system capacity
128GB, At the same time continue to support DDR4.

   Market survey organization Omdia Data display of ,DDR5 The market demand of memory will be in 2021 The year began to appear ,2022 Global share will break through in 10%,2024 It can be reached in one year 43%.
