Samsung announces the industry's largest capacity memory chip '32Gb DDR5 DRAM', making it possible to create up to 1TB of DRAM and reduce power consumption

Samsung, which

announced the start of mass production of 16Gb (gigabit) DDR5 DRAM using the industry's most advanced 12nm class process in May 2023, has announced `` 32Gb DDR5 DRAM,'' which has twice the capacity of 16Gb DDR5 DRAM . Samsung claims that this is the industry's largest capacity, and that it is a technology that will enable the realization of DRAM modules of up to 1TB.

On September 1, 2023 local time, Samsung announced that it has developed the industry's first and largest capacity 32Gb DDR5 DRAM using a 12nm class process. Samsung says this 'consolidates Samsung's leadership in next-generation DRAM technology and marks the next chapter in high-capacity memory.'

'Our 32Gb DRAM based on 12nm class process is a solution that can realize DRAM modules up to 1TB, and is a growing demand for large-capacity DRAM in the AI era,' said Hwang Sangjun, executive vice president of DRAM products and technology at Samsung. It is also the ideal solution to meet these needs. Samsung continues to push the limits of memory technology and develop DRAM solutions through differentiated process and design techniques.'

In addition, since Samsung is already manufacturing a 512GB DRAM module using 16Gb DDR5 DRAM, a 1TB DRAM module can also be realized by using 32Gb DDR5 DRAM with twice the capacity. However, this DRAM uses RDIMM .

Samsung developed its first DRAM in 1983, and the capacity of the DRAM developed at that time was only 64 Kb (kilobit). Forty years have passed since then, and the capacity of DRAM developed by Samsung has increased by 500,000 times. Samsung achieves cutting-edge processes and technologies by increasing memory density and optimizing designs. This results in the industry's highest capacity 32Gb DDR5 DRAM for a single DRAM chip, which is twice the capacity of 16Gb DDR5 DRAM in the same package size.

DDR5 128GB DRAM modules manufactured using 16Gb DDR5 DRAM used a technology called

Through Silicon Via (TSV) , but with the new 32Gb DDR5 DRAM, 128GB DRAM modules can be manufactured without TSV. can be manufactured. This can reduce power consumption by approximately 10% compared to a DDR5 128GB DRAM module using 16Gb DDR5 DRAM. Therefore, 32Gb DDR5 DRAM seems to be the optimal solution in cases where power efficiency is important, such as in data centers.

In addition, Samsung plans to expand its lineup of large-capacity DRAM modules that meet various demands based on 32Gb DDR5 DRAM using a 12nm class process. The company plans to supply 32Gb DDR5 DRAM not only to data center products, but also to customers who require AI and next-generation computing.

Samsung has not disclosed the data transfer speed of 32Gb DDR5 DRAM, but for 16Gb DDR5 DRAM manufactured with the same 12nm class process, the data transfer speed is 7200MT/s. Regarding this data transfer speed, technology media HotHardware explained, ``This number significantly exceeds the data transfer speed of memory supported in module form in general Intel and AMD systems.''

Samsung plans to start mass production of 12nm class process 32Gb DDR5 DRAM by the end of 2023.
