Samsung already manufactures hbm2 memories from 8 gb to 2.4 gbps

Samsung has taken a major new step in high-bandwidth stacked memory technology, better known as HBM. The Korean firm has already started mass production of second-generation HBM2 memory stacks with a capacity of 8 GB at a speed of 2.4 Gbps.

Samsung starts production of second generation HBM2

Samsung has reported that it has already started mass manufacturing its second-generation HBM2 memory chips, these come with a capacity of 8GB per stack, and an effective operating frequency of 2.4Gbps to accelerate the capabilities of the next-generation GPU-based supercomputing.

This new second-generation HBM2 memory operates at a voltage of 1.2V, allowing for greater energy efficiency compared to the first-generation HBM2 that used the same voltage, but only reached a rate of 1.6 Gbps. Thanks to this, a single stack of this new memory achieves a bandwidth of 307 GB / s, which is almost ten times more than the GDDR5 memory that has been used in recent years in almost all the graphics cards on the market.

To make this possible, TSV (Through Silicon Via) technology has been used to make more than 5, 000 connections per die, something that has not been easy to achieve successfully in such a small package and that demonstrates Samsung's leadership.

In this way Samsung makes possible a new generation of graphics cards with a memory bandwidth of up to 1.2 TB / s, which will greatly increase its capabilities. For now, gaming cards are not expected to make use of this new technology, for them the GDDR6 is waiting.
