Understanding Kingston 16Gbit DRAM Technology

Published 4th December 2020 | Article by KingstonMemoryShop | Posted in RAM Memory

Kingston | 16Gbit DDR4 DRAM transition guide

At the beginning of Q4 2019, DRAM semiconductor suppliers started introducing the next generation high density DRAM for DDR4. This means that DRAM is transitioning from 8Gbit to 16Gbit technology.

Based on new wafer lithography (below 20nm), these new components:

Double the RAM density available. Allow higher capacity memory modules to be created. Provide lower power usage (per Gigabyte).

DRAM differences between Gbit and GB:

GB (Gigabyte)
  • This measures the density of the chip within a DRAM module
  • The density of a DRAM chip is measured in Gigabits (Gbit)
  • A bit is the smallest unit measured in computing
  • A 16Gbit DRAM chip can hold 16 billion bits of data

GB (Gigabyte)
  • This measures the density of the chip within a DRAM module
  • The density of a DRAM chip is measured in Gigabits (Gbit)
  • A bit is the smallest unit measured in computing
  • A 16Gbit DRAM chip can hold 16 billion bits of data

How we can build the same capacity with different density chips

8GB DRAM Module:

8Gbit DRAM Chip (1024x8) in 1 Rank

8 DRAMs
  • 64bits

16Gbit DRAM Chip (1024x16) in 1 Rank

4 DRAMs
  • 64bits

 

 

Module Types with 16Gbit DRAM

  • 8GB Unbuffered DIMM / SODIMM (1Rx16)

    16GB Unbuffered DIMM / SODIMM (1Rx8)

    32GB Unbuffered DIMM / SODIMM (2Rx8)

    16GB ECC Unbuffered DIMM / SODIMM (1Rx8)

    32GB ECC Unbuffered DIMM / SODIMM (2Rx8)

    16GB ECC Registered DIMM (1Rx8)

    32GB ECC Registered DIMM (2Rx8)

    32GB ECC Registered DIMM (1Rx4)

    64GB ECC Registered DIMM (2Rx4)

Whilst this transition provides many benefits to server and computing power, not all platforms are supported with this new technology, so here is a guide to the key things to remember:
